Detailed description:

Hi all,
I'm no kernel expert, I hope I made no mistakes in this report. It seems to me that a bug was added to the MPT Fusion driver in 2.6.26 (rc7).

I compiled 2.6.26-rc7 on a machine with controller LSI53C1080 and it cannot boot. Doing the same with 2.6.25, basically the same config file, boots without problems.

I tried to forward-port the Fusion driver from 2.6.25 to 2.6.26-rc7 by simply copying over the directory drivers/message/fusion/ from 2.6.25 to 2.6.26-rc7 but unfortunately this doesn't compile, so I am stuck not being able to use 2.6.26 on this machine (actually I have not tried versions of 2.6.26 earlier than rc7... I don't have much time now).

I connected a serial cable in order to obtain the boot error message. I obtained two of those on different boots. I will paste these at the end of this post.


This is the verbose lspci of the controller (obtained with 2.6.25):

This is the boot error message obtained with serial cable. I left it running for 8 minutes for this. It loops so the message never ends.

mpt-fusion shouldn't oops, no matter what acpi did to it.
Comment 2 Kurk 2008-07-06 13:28:48 UTC
The ACPI thing, if it is a bug (I didn't realize that) I think was introduced much earlier than 2.6.26. I think the same ACPI error strings are visible in 2.6.24 and probably even much earlier kernels. However they don't prevent booting. Thank you.
Comment 3 Adrian Bunk 2008-07-06 13:50:58 UTC
Thanks for this information.

Please open a separate bug for the ACPI problem.
Comment 4 Kurk 2008-07-07 02:36:45 UTC
OK I have opened bug 11049 for the ACPI thing.
Thank you.

You removed everyone from cc.  Please don't do that - there's not much
point in asking me to do things - this bug is reported by
kurk@shiftmail.org.

I don't know what "we do not assist with compiling drivers" can possibly
mean.  Eric, can you please help here?

heh, well, cc'ing a support line on a technical bug report isn't
necessarily conducive to producing useful results ... what we're
discussing is probably already at level 4 or 5 (the real engineering
problems).  Support calls go in at levels 1-3 (as in consult manual and
spit out canned response before triaging for escalation).

That said, this line:

mptbase: ioc0: ERROR - Doorbell ACK timeout (count=4999), IntStatus=80000009!

is absolutely characteristic of a lost interrupt.

With the current LSI driver, we have two possible causes for this.  One
is the usual ACPI screw up that we never seem to be able to fix.  The
other is that the driver recently enabled MSI (commit
23a274c8a5adafc74a66f16988776fc7dd6f6e51 in v2.6.26-rc1).  For the
former, just follow the usual ACPI screw up recipe.  For the latter, you
should see this message in the boot up:

mptbase: ioc0: PCI-MSI enabled

MSI can be turned off again by using the module parameter
mpt_msi_enable=0.

Unfortunately, the true fix is to find out if the motherboard really has
a global MSI problem (and I know MSI works with the LSI because I have a
1030 in an ia64 system here working just fine) and add it to the PCI
quirks file as unable to use MSI.

Which ACPI screw up is that?  And what's the usual recipe?

I know about the ancient "pci=routeirq" recipe, but as far as I know,
there are no current problems that require that.

The usual screw up where subtle ACPI breakage from release to release
causes some IRQs to get misrouted.

Usually you start with noacpi and cycle through the pci routing options

If you actually read this bug report, you'll see there was a message

ACPI: Resource is not an IRQ entry

Just before the fusion IRQ failed to get delivered, so I think it's a
good indicator that there *are* ACPI problems ...

Don't worry, I wasn't trying to talk you out of an ACPI bug report;
I just wanted to get enough specifics so I could see whether it was
something I could fix.

These messages also happen with 2.6.25, where the MPT Fusion driver
worked, so Kurk opened a separate bugzilla,
  http://bugzilla.kernel.org/show_bug.cgi?id=11049
for them.

Yakui Zhao thinks the messages are harmless because they're
related to interrupt link devices that we don't use in IOAPIC mode,
and given that the driver works in 2.6.25, that seems plausible
to me.

Regardless, the messages are alarming and annoying.  I'd like
to understand them better, but I'll pursue that in the 11049
bugzilla.

That's fixed in the scsi-rc-fixes tree ... but it's a symptom, not a
cause.  If essential storage is on this adapter, the system will still
be unbootable.

This may  be a problem due to enabling MSI for SPI controllers. I have posted another message in the list providing the correction patch which is already in scsi-misc tree. 
If the problem is gone with changing the module parameter mpt_msi_enable=0 or by applying the patch http://marc.info/?l=linux-scsi&m=121131228827682&w=4 then it might be due to MSI enabling.

Hi Bjorn,
what I pasted in, it is absolutely the complete log obtained with the serial cable. I did not modify it in any way or cut away parts. As I wrote, I obtained it twice, once stopping the boot after 8 minutes, the other stopping after 5 (and stack traces are slightly different in the two boots as you can see). The error messages loop as you can see and never end so it is necessary to stop that after a while. The other attachments like dmesg (2.6.25), lspci (2.6.25), .config yes, I grepped or cut them, but not the serial dump.

(Is it ok if I reply from the web interface or should I do via email? Sorry it's the first time I use bugzilla.kernel.org)

Boot messages with quiet disabled, serial dump
Comment 15 Kurk 2008-07-10 07:25:16 UTC
Bjorn,
you were right, the serial dump was not complete because there was the 
"quiet" option specified as kernel parameter.
I just uploaded the full (non-quiet) serial dump as attachment on the 
bugzilla web interface.
Thank you
Comment 16 Kurk 2008-07-10 07:25:22 UTC
Hi all,
Good news! James and Sathya were correct, the bug is related to MSI: 
specifying mpt_msi_enable=0 as option for the mptbase module solves the 
problem and the system can boot as usual.

Having said this, do you still want me to try a patch, or perform some 
additional test?

Just out of curiosity: do you intend to eventually modify the kernel so 
to "support" and work around buggy hardware like the one we have (IBM 
xSeries 335), so that Linux can work out of the box even on this hardware?

Thank everybody for your help

Another good news: I confirm that yes, the problem is also fixed by the 
patch linked above by Sathya, and in that case it is not needed to 
specify option mpt_msi_enable=0 for mptbase. Any one of the two (patch 
or option) is enough to fix the problem.
It would be nice to see this patch in the final release of the 2.6.26 kernel
Thank you

James, shouldn't we put that into 2.6.26?

That whole patch series looks pretty desirable actually..

I'm still not sure ... if it's a fault on the board with MSI, then yes,
we need it in ... although the form would then be wrong because we
probably should be identifying the faulty parts and blacklisting them.

If it's actually a fault on the motherboard with MSI, then no, this
isn't the patch series that should be in we need the motherboard strings
to blacklist it.

Unfortunately, I can't seem to get an answer out of LSI on this
question, It looks like the commit will cherry pick easily enough ...
although now I look at it the parameter's description is wrong.

> That whole patch series looks pretty desirable actually..

Well, it was billed as a driver update ... and it has a lot more than
just trivial changes, so on an eve of release quality issue, I'd tend to
say that wouldn't be a good idea.

I did a recheck on this, except FC 919X and 929X boards, everything else should work fine with MSI. Hence the SPI boards (1030) should work with MSI and the problem might be with the motherboard.
But we would like to keep the MSI disabled for SPI controllers since we have not tested internally with MSI and FC enabled by default for them in our recent drivers.
So I would like to request to pull in the patch to disable MSI for SPI & FC.
-Thanks
Sathya

Right ... that's why I was asking ... my 1030 works fine with MSI.  If
there's a fault with the FC boards, then certainly they should have MSI
disabled.

The motherboard was my suspicion ... especially as older ones have SPI
and newer ones have SAS (and the older ones are most likely to have MSI
faults).  However, I think you can see from our point of view that if
the problem is the motherboard, disabling MSI in the fusion is the wrong
way to fix it.  If we do it this way, we'll promptly get another slew of
nasty bug reports for the next driver that enables MSI and doesn't work
on this platform

Yes, we'll do that ... I'll also see if the PCI maintainer can determine
the information needed to blacklist the motherboards so that we don't
get this all over again with them and a different driver.
