Software Environment:

Problem Description: see dmesg & kernel config attached.

My SATA drives are not detected and the system does not boot.
I have two drives that compose a software RAID1 array.
Drives are attached to SATA1 and SATA2 connectors while SATA3 and SATA4 are 
free.
No IDE devices connected apart from a DVD-RW.

I'd like to have this fixed within 2.6.19 stable.

Comment 4 Tejun Heo 2006-11-28 17:42:17 UTC
dmesg doesn't contain ahci/libata related part.  please post full dmesg.  if you
can't get the rootfs mounted and have access to another machine, the easiest way
would be using netconsole (Documentation/networking/netconsole.txt).
Comment 5 Adrian Bunk 2006-11-28 19:27:08 UTC
It might be enough to use "dmesg -s 1000000" and/or increase
CONFIG_LOG_BUF_SHIFT  instead of using netconsole.
Comment 6 Fabio Erculiani 2006-11-28 23:25:37 UTC
Ok, will do.

But JFYI. it hangs here (for about 5 minutes):

Please test the attached patch.
Comment 9 Fabio Erculiani 2006-11-28 23:40:04 UTC
ok will do ASAP during today.
Comment 10 Fabio Erculiani 2006-11-29 08:58:55 UTC
ok, so, I'm attaching the dmesg with the patch "don't power down on deinit" 
applied. No luck. Same behavior.
Devices are not initialized, though there aren't /dev/sda nor /dev/sdb in /dev.

If the dmesg output is not enough, I could try to enable debug and/or change 
CONFIG_LOG_BUF_SHIFT, since I can't use netconsole ATM.

Oh, JFYI, using genkernel and without the root device available (/dev/md0), I 
can use busybox to do common tasks, like saving dmesg output.

Comment 16 Fabio Erculiani 2006-11-30 05:51:16 UTC
I tried 2.6.19 (final). The problem is still there.
Tejun, your patch does not apply against it. I'm trying to find the right piece 
of code where I can copy/paste those lines btw.
Comment 17 Fabio Erculiani 2006-11-30 05:54:36 UTC
I am now trying to recompile the kernel injecting the patch here:

{
        struct ahci_port_priv *pp = ap->private_data;
        u8 *d2h_fis = pp->rx_fis + RX_FIS_D2H_REG;
        struct ata_taskfile tf;
        void __iomem *mmio = ap->host->mmio_base;
        void __iomem *port_mmio = ahci_port_base(mmio, ap->port_no);
        int rc;

        DPRINTK("ENTER\n");

        ahci_stop_engine(port_mmio);

        /* vt8251 needs CLO even before hardreset */
        if (ahci_check_status(ap) & (ATA_BUSY | ATA_DRQ)) {
                rc = ahci_clo(ap);
                /* If CLO fails, whine but continue.  Hardreset is our
                 * final line of defense anyway.
                 */
                if (rc)
                        ata_port_printk(ap, KERN_WARNING, "vt8251_hardreset: "
                                        "CLO failed (%d)\n", rc);
        }


        /* clear D2H reception area to properly wait for D2H FIS */
        ata_tf_init(ap->device, &tf);

dmesg from 2.6.18.3 (working kernel)

This is the dmesg output from 2.6.18.3, where all is working fine.
Comment 19 Tejun Heo 2006-11-30 07:10:18 UTC
Ah.. I thought you were testing -mm.  Sorry.  Can you please test
2.6.19-rc6-mm2?  Please test whether the above patch makes any difference.  You
can easily get -mm using ketchup.  (www.selenic.com/ketchup/wiki/)  Just do
'ketchup -G 2.6.19-rc6-mm2.
Comment 20 Fabio Erculiani 2006-11-30 09:45:02 UTC
I'm a gentoo hardcore user, don't worry... installing mm-sources 
2.6.19_rc6-mm2 :)

Will there be any chance to see this (possible) fix "backported" to 2.6.19 
vanilla? maybe 2.6.19.1 ?

I'm going to report the results here in a hour or two.
Comment 21 Fabio Erculiani 2006-11-30 11:40:39 UTC
no, no luck with 2.6.19-rc6-mm2 nor with the patch "CLO-before-hardreset". Same 
dmesg, same behavior.
Could you tell me which debug option I should enable?
Comment 22 Tejun Heo 2006-11-30 22:38:39 UTC
Please try the followings.

* I'm attaching a patch against v2.6.19.  Apply it and see what happens.  Please
report full dmesg whether it works or not.

* If that doesn't work, try usual IRQ options - noapic, pci=noacpi

Thanks.

debug patch
Comment 24 Fabio Erculiani 2006-12-03 14:43:54 UTC
Ok here I am,
I applied the patch, but I didn't see any new debug info on dmesg (??).
With the patched kernel, I was able to boot by adding "irqpoll".
I tried to enable/disable APIC from BIOS, same behavior, it boots with irqpoll. 
BUT!: I get dmesg spammed by this error:
[...]
[  149.742116] APIC error on CPU0: 08(08)
[  149.752146] APIC error on CPU0: 08(08)

[  149.799556] APIC error on CPU0: 08(08)
[  149.799977] APIC error on CPU0: 08(08)
[  149.806430] APIC error on CPU0: 08(08)
[  149.816113] APIC error on CPU0: 08(08)

[  149.831612] APIC error on CPU0: 08(08)
[  149.841141] APIC error on CPU0: 08(08)
[...]

So, as usual, I came back to 2.6.18, that boots fine without any fancy boot 
parameter, without any particular error (see dmesg attached) BUT, if I disable 
APIC from BIOS (never done before), even 2.6.18 does not boot.

So:
2.6.19 without parameters (APIC on/off) = NO BOOT
2.6.19 with irqpoll (APIC on/off) = BOOT, libata works without any problem BUT 
a lot of APIC errors 
2.6.18 without parameters (APIC on) = BOOT
2.6.18 without parameters (APIC off) = NO BOOT 
Comment 25 Tejun Heo 2006-12-03 17:01:12 UTC
If you specify irqpoll, does unpatched 2.6.19 boot properly?
Comment 26 Fabio Erculiani 2006-12-03 22:29:17 UTC
yes, it does. But then, dmesg gets spammed with the APIC errors above and nvidia

I know that's not your problem, but I write this JFYI :)

I've got any problem at all with 2.6.18.3 (vanilla). All is working fine with that.
Comment 27 Fabio Erculiani 2006-12-03 22:32:28 UTC
I'd say that I've not any problem at all with 2.6.18.3 ;)
Comment 28 Tejun Heo 2006-12-03 22:44:50 UTC
I don't think it's libata bug.  2.6.18 dmesg has VIA IRQ fixup message while
2.6.19 doesn't.  That might be causing it.  CC'ing Alan Cox.
Comment 29 Fabio Erculiani 2006-12-03 23:52:54 UTC
nice, so we might have found the problem :)
Comment 30 Fabio Erculiani 2006-12-04 00:01:23 UTC
Ok, I might have found the cause:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=09d6029f43ebbe7307854abdae204c25d711ff94

it is written:
" It runs the quirk on all VIA hardware, but *only* if a VIA
southbridge was detected on the system."

and, on 2.6.19 dmesg I have:
[  297.434386] via: Unknown VIA SouthBridge, disabling.

I am now trying to revert that patch and see if it works.
Comment 31 Alan 2006-12-04 04:14:28 UTC
The current -mm tree should have the patch I did based on Daniel Drake's patch
which applies the quirks only in the cases it should matter and doesn't trash
other stuff.

The "Unknown southbridge" message wouldn't come from the PCI quirks. It comes
from the VIA driver if it cannot find your bridge in the list of devices it
knows about. That sounds unrelated but doesn't explain why 2.6.18.3 worked (or
was that a gentoo kernel which is nothing like the default ?)

Attach an lspci -vxxx please. I want to see the pci id/rev of the southbridge in
particular
Comment 32 Fabio Erculiani 2006-12-04 05:13:35 UTC
yes sorry, I am using gentoo-sources-2.6.18-r4:
http://dev.gentoo.org/~dsd/genpatches/patches-2.6.18-4.htm

the only VIA IRQ releated patch is this:
2500_via-irq-quirk-revert.patch	http://bugs.gentoo.org/138036	Revert recent VIA
IRQ quirk change

Anyway, the 2.6.19 releases that I tested were:
- 2.6.19 vanilla
- 2.6.19-rc6-mm2

attaching lspci -vxxx as requested. Alan, should I try 2.6.19 with the VIA IRQ
patch described on #30 reverted?

Comment 34 Alan 2006-12-04 06:03:14 UTC
Ok thats the lspci -vxx explains the non-detection of the PATA ports, but not
the SATA/AHCI problem - try reverting the IRQ patch as I'm not sure what is
going on and it might be a good clue.
Comment 35 Fabio Erculiani 2006-12-04 06:44:10 UTC
ok, I've already compile the kernel with that VIA IRQ patch reverted but I need
to get home before trying to reboot.

Anyway, Alan, about the APIC errors on #24 ? any clue?
Comment 36 Fabio Erculiani 2006-12-04 09:06:08 UTC
no, reverting patch listed on #30 does not help.
Comment 37 Fabio Erculiani 2006-12-06 01:48:19 UTC
Just tell me what I could do for you, and will be done.
Comment 38 Fabio Erculiani 2006-12-10 14:18:30 UTC
@all:
I've found that adding "pci=nomsi" fixed the boot/AHCI/APIC problems.

Comment 40 Tejun Heo 2006-12-10 17:43:01 UTC
MSI related code in AHCI has not changed between .18 and .19.  This must be VIA
chipset related problem.  Changing Category.  Anyone knows who knows this stuff?
Comment 41 Simon Farnsworth 2006-12-16 15:42:43 UTC
I have a much more severe version of the same problem. In my case, the 
motherboard is an ASUS A8V-X.

When I try and boot vanilla 2.6.19.1 (instead of Gentoo's 2.6.18-r4), the 
VT8251 does not generate interrupts correctly; booting with pci=nomsi does not 
fix this; nor does adding "noapic acpi=off pci=nomsi" (although interrupt 
numbers change for all three boots - MSI, IO-APIC, XT-PIC, showing that the 
kernel is parsing the options).

I've tried editing drivers/pci/quirks.c to print a message rather than 
returning if new_irq is outside the legacy range; this message triggers in all 
boots but "noapic acpi=off pci=nomsi", but does not solve the problem. I can't 
find any other VIA specific quirks in that file that trigger on 2.6.18 but not 
on 2.6.19.

    [PATCH] libata: improve driver initialization and deinitialization

    Implement ahci_[de]init_port() and use it during initialization and
    de-initialization.	ahci_[de]init_port() are supersets of what used to
    be done during driver [de-]initialization.	This patch makes the
    following behavior changes.

    * Per-port IRQ mask is cleared on driver load as done in other
      drivers.	The mask will be configured properly during probe.

    * During init_one(), HOST_IRQ_STAT is cleared after masking port IRQs
      such that there is no race window.

    * CMD_SPIN_UP is cleared during init_one() instead of being set.  It
      is set in port_start().  This is more consistent with overall
      structure of initialization.  Note that CMD_SPIN_UP simply controls
      PHY activation.

    * Slumber and staggered spin-up are handled properly.

    * All init/deinit operations are done in step-by-step manner as
      described in the spec instead of issued as single merged command.

    Original implementation is from Zhao, Forrest <forrest.zhao@intel.com>

Just in case anyone's still following this; 
a718728f9e40ec79c0879ec6509a54fee214f5b2 brings me to the same position as the 
original reporter. AHCI now works, but not with MSIs enabled.

i don't what that the logic is to enable MSIs but given i have many
systems where the chipsets in theory support this but it doesnt work i
think it should default to off.  we can whitelist systems where it's
known to work or let people explicitly turn it on until we figure out
sane heuristics for this

> /me grasps for an MSI maintainer.  Hi, Eric.

Could I get lspci -s 0:02.0 -xxx

My hunch is that the BIOS failed to setup the PCI-E to HT
msi mapping properly.

If that is the case we should be able to simply add an x86 quirk
that fixes this in the kernel for all devices that have a
PCI-E to HT mapping.  Since the value that needs to be in
there is architecturally defined and it is a standard HT device.

I think what happened to cause this is that the attempt was
to require a white list for MSI on systems that don't have
PCI-E and a blacklist on all x86 systems that do have PCI-E.

And since this chipset supports PCI-E and is not blacklisted
we support it.

If it's not a misprogrammed MSI mapping capability, VIA messed
up and we need to black list this chipset.

Eric

Comment 47 Simon Farnsworth 2007-01-31 23:50:11 UTC
On my system, lspci -s 0:02.0 -xxx displays nothing, so I did lspci -xxx as 
well. Note that MSI works fine on 2.6.18.5, so it's a regression on a system 
that worked before.

No wonder this bug is confusing there is discussion about 2
separate issues that have similar symptoms.

Could I please get a lspci -vvv for the ASUS-VX as well.
It's better if I don't have to decode registers by hand.

From what little I can see there does not appear to be
a msi-mapping capability anywhere visible.

If that is the case then we don't have generic registers
for controlling the conversion of MSI messages to HT
interrupt packets.  So it may be all that we can easily
do is black list this and complain to ASUS.

I don't have a contact at VIA for getting their datasheets
which rules out using non-generic registers.

Comment 49 Christopher Harrington 2007-04-30 21:12:56 UTC
Just adding another me-too. If wanted, I'll post dmesg/.config/lspci/whatever,
but I won't clutter if it's not needed.
Comment 50 Natalie Protasevich 2007-07-08 18:23:19 UTC
Any updates on this problem?
Simon, were you able to get information as requested in #48? Thanks.
Comment 51 Adam Felson 2007-07-08 18:55:54 UTC
  append="pci=nomsi" is a workaround, making it a sev 3 bug instead of a sev 1 bug
Comment 52 Simon Farnsworth 2007-07-10 01:17:02 UTC
My VIA machine is currently in storage, due to homelessness; I'll provide lspci -vvv information once I've got it available again (at least another month, if not two months to go).
Comment 53 Andrew Morton 2007-08-02 15:47:08 UTC
Adam, which kernel version requires the pci=nomsi wrokaround?
Comment 54 Adam Felson 2007-08-02 17:03:59 UTC
Every version since 2.6.17 has needed it.  I run gentoo and 2.6.22-gentoo-r2 still has the bug.  (I just tried it without and with pci=nomai)
Comment 55 Tejun Heo 2007-08-14 00:45:23 UTC
So, am I right in that assuming all that's needed is blacklisting MSI on the affected chipsets?
Comment 56 Simon Farnsworth 2007-09-03 07:38:47 UTC
The delayed response to #48; note that I've added a PCI card since then:

append="pci=nomsi" is a workaround, making it a sev 3 bug instead of a sev 1
bug
==> works for me, too!

==> Asus Mainboard: Asus A8V-XE /w VIA® K8T890 + VIA VT8251

with "pci=nomsi" - works
with "acpi=noirq" - does not work
with "irqpoll" - works

I'm ging to attach 'hwinfo --all' && 'boot.msg'

Comment 60 Tejun Heo 2008-01-02 00:33:01 UTC
Eric, ping.
Comment 61 Natalie Protasevich 2008-01-02 01:35:01 UTC
Phillip, can you please attach /proc/interupts for nomsi and irqpoll cases, and for working 2.6.18 if possible. It might be useful to compare the two. With irqpoll the SATA interrupt probably gets piggy ride on the shared IRQ (with USB it looks like) 
Comment 62 Natalie Protasevich 2008-04-05 20:52:37 UTC
Can any of the reporters confirm the problem is still present with latest kernel?
Comment 63 Adam Felson 2008-04-08 14:43:23 UTC
The problem is still present, tested with linux-2.6.24 as distributed by gentoo's emerge (2.6.24-gentoo-r3)

When booting without kernel option "pci=nomsi", SATA drives aren't detected.

There's a workaround; the severity should be lowered.
Comment 64 Tejun Heo 2008-04-09 17:42:32 UTC
Eric, can we just blacklist MSI on the board?  Does anyone know whether it's specific to the board/bios or generic chipset problem?
Comment 65 Thomas Gleixner 2008-09-05 05:15:14 UTC
Has anything moved here ? Would be nice to have a report against 2.6.27-rc5, before we blacklist it.

Boot log with and without pci=nomsi preferrably catched via serial console might be helpful.

Comment 67 Jon 2009-10-05 22:54:41 UTC
I know this has been closed, but... any update on this?  I've got nearly the same issue (SATA link down; SATA works only with pci=nomsi) on an XFX mobo with a GeForce8200 chipset w/SATA set to AHCI.  The relevant lspci -vvnn:

I'm running 2.6.28-15/Ubuntu Jaunty.  

I'll happily provide any information you need because my system does go ahead and boot after it displays that series of ata errors/timeouts, since my OS is loading from a Sil3114 RAID controller in a PCIe slot.

I ask because I'd like to be able to use PCI-passthrough with KVM, and I gather this becomes significantly harder, if not impossible, with MSI disabled.
Comment 68 Tejun Heo 2009-10-06 05:33:59 UTC
Can you please file a new bug report and attach kernel boot log and full output of "lspci -nnvv"?
Comment 69 Jon 2009-10-06 13:49:26 UTC
I will as soon as I get home, and I'll link to it here for the reference of anyone who stumbles upon this.  

I also updated my kernel with a backported version of the Ubuntu 9.10/2.6.31-11-server (Karmic) kernel last night, and the bug hasn't been fixed--I still lose all of my SATA if I remove the pci=nomsi boot flag.  I've had the issue since I bought my motherboard, and at that time I was running 8.10/2.6.27.
