Latest working kernel version: 2.4.x was far less problematic Earliest failing kernel version: i didn't try the versions inbetween, the first update was already at 2.6.24 Distribution: Archlinux Hardware Environment: relevant parts: motherboard - MSI P965 Neo, hard disk - 200GB ata disk , cdrw/dvdrw LG Software Environment: not an userspace software problem Problem Description: I'm getting long boots due to ata recognition problems as shown below, in the 2.4.x versions it was unnoticable, it only did one soft reset which prolonged boot time by 5 seconds which was managable. Important thing to note is that once it finally boots it works just as well as it did in 2.4.x, showing no signs of failirue, but boot time is just huge. Additional information and similar problems can be found here if interested: http://bbs.archlinux.org/viewtopic.php?pid=379139#p379139 The link above just shows problems other people have that weren't connected to my distribution which might give some insight to the issue. Issue represented itself on multiple distributions using newest (2.6.x) kernel, some to name: Archlinux, Fedora 8. important dmesg output part: scsi0 : pata_jmicron scsi1 : pata_jmicron ata1: PATA max UDMA/100 cmd 0xbf00 ctl 0xbe00 bmdma 0xbb00 irq 17 ata2: PATA max UDMA/100 cmd 0xbd00 ctl 0xbc00 bmdma 0xbb08 irq 17 Switched to high resolution mode on CPU 1 Switched to high resolution mode on CPU 0 ata1.00: ATA-7: ST3200826A, 3.06, max UDMA/100 ata1.00: 390721968 sectors, multi 0: LBA48 ata1.01: ATAPI: HL-DT-ST DVDRAM GSA-4120B, A101, max UDMA/33 ata1.00: configured for UDMA/100 ata1.01: configured for UDMA/33 scsi 0:0:0:0: Direct-Access ATA ST3200826A 3.06 PQ: 0 ANSI: 5 scsi 0:0:1:0: CD-ROM HL-DT-ST DVDRAM GSA-4120B A101 PQ: 0 ANSI: 5 ahci 0000:02:00.0: version 3.0 ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16 ahci 0000:02:00.0: AHCI 0001.0000 32 slots 2 ports 3 Gbps 0x3 impl SATA mode ahci 0000:02:00.0: flags: 64bit ncq pm led clo pmp pio slum part PCI: Setting latency timer of device 0000:02:00.0 to 64 scsi2 : ahci scsi3 : ahci ata3: SATA max UDMA/133 abar m8192@0xfdbfe000 port 0xfdbfe100 irq 16 ata4: SATA max UDMA/133 abar m8192@0xfdbfe000 port 0xfdbfe180 irq 16 ata3: SATA link down (SStatus 0 SControl 300) ata4: classification failed ata4: reset failed (errno=-22), retrying in 8 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 35 secs ata4: limiting SATA link speed to 1.5 Gbps ata4: classfication failed, assuming ATA ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 310) ata4.00: qc timeout (cmd 0xec) ata4.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata4: failed to recover some devices, retrying in 5 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 35 secs ata4: classfication failed, assuming ATA ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 310) ata4.00: qc timeout (cmd 0xec) ata4.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata4: failed to recover some devices, retrying in 5 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 35 secs ata4: classfication failed, assuming ATA ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 310) ata4.00: qc timeout (cmd 0xec) ata4.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata4: failed to recover some devices, retrying in 5 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 10 secs ata4: classification failed ata4: reset failed (errno=-22), retrying in 35 secs ata4: classfication failed, assuming ATA ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 310) ata_piix 0000:00:1f.2: version 2.12 ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (level, low) -> IRQ 19 ata_piix 0000:00:1f.2: MAP [ P0 P2 P1 P3 ] PCI: Setting latency timer of device 0000:00:1f.2 to 64 scsi4 : ata_piix scsi5 : ata_piix ata5: SATA max UDMA/133 cmd 0xfa00 ctl 0xf900 bmdma 0xf600 irq 19 ata6: SATA max UDMA/133 cmd 0xf800 ctl 0xf700 bmdma 0xf608 irq 19 ata5: SATA link down (SStatus 0 SControl 300) ata6: SATA link down (SStatus 0 SControl 300) ACPI: PCI Interrupt 0000:00:1f.5[B] -> GSI 19 (level, low) -> IRQ 19 ata_piix 0000:00:1f.5: MAP [ P0 -- P1 -- ] PCI: Setting latency timer of device 0000:00:1f.5 to 64 scsi6 : ata_piix scsi7 : ata_piix ata7: SATA max UDMA/133 cmd 0xf300 ctl 0xf200 bmdma 0xef00 irq 19 ata8: SATA max UDMA/133 cmd 0xf100 ctl 0xf000 bmdma 0xef08 irq 19 ata7: SATA link down (SStatus 0 SControl 300) ata8: SATA link down (SStatus 0 SControl 300) usbcore: registered new interface driver usbfs entire dmesg output: Linux version 2.6.25-ARCH (root@desktop) (gcc version 4.3.0 (GCC) ) #1 SMP PREEMPT Sun Jun 1 15:04:51 CEST 2008 Command line: root=/dev/sda1 ro vga=791 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f000 (usable) BIOS-e820: 000000000009f000 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000007fee0000 (usable) BIOS-e820: 000000007fee0000 - 000000007fee3000 (ACPI NVS) BIOS-e820: 000000007fee3000 - 000000007fef0000 (ACPI data) BIOS-e820: 000000007fef0000 - 000000007ff00000 (reserved) BIOS-e820: 00000000e0000000 - 00000000f0000000 (reserved) BIOS-e820: 00000000fec00000 - 0000000100000000 (reserved) Entering add_active_range(0, 0, 159) 0 entries of 256 used Entering add_active_range(0, 256, 524000) 1 entries of 256 used end_pfn_map = 1048576 DMI 2.4 present.

The factory one I got was quite weird, it kept giving me GRUB errors on every single distribution - if you can even attach this to Linux. It remained unfixed even after the Linux install day so it wasn't something that was a beginners mistake, however I managed to fix it by getting newest BIOS drivers. Still, I had changed multiple computers by now, and this one reports drivers in a weird day. Instead of printing my LG cd/dvd and my hard drive in the first part of the BIOS screen, i.e IDE Primary Master, IDE Primary Slave, IDE Secondary... it prints it out on the nest screen with a JMICRON advert on top. But it does detect them correctly there and on boot. I guess that's because the motherboard has about 5 SATA pins and only one PATA, so my components must be considered legacy? Even if my BIOS is retarded, my main argument is that in pre 2.6.x kernels such as 2.4.x, it did only one single ata reset which was fine 5~extra seconds, now it just keeps reseting for 5~mins, which is annoying.
Created attachment 16498 [details] jmb361.patch JMB361 is reporting incorrect port map. Please test the attached patch.
awesome, simply brilliant, the patch you supplied works, don't receive any kind of errors i can see, thank you a question though, is this patch going to be put in future kernel releases, or is this some kind of my own personal problem i should worry about? thanks anyway
It's jmb361 reporting the wrong port map value to the driver && your machine doesn't have anything personal against you. :-) I'll forward the patch upstream. Thanks.
Oh.. can you please attach kernel boot log?
Created attachment 16524 [details] kernel_boot
I just assumed you wanted the log now it's fixed
Yeap, that looks fine. Thanks.
Created attachment 16705 [details] updated patch I have the same hardware (JMB361, same PCI ids) but this fix didn't work for me. The reason is that a few lines down in drivers/ata/ahci.c there's a check that resets port_map back to 0 because the number of bits in it don't match the number of ports advertised in cap: [ 30.118089] ahci 0000:02:00.0: JMB361 has only one port, port_map 0x3 -> 0x1 [ 30.118094] ahci 0000:02:00.0: nr_ports (2) and implemented port map (0x1) don't match, using nr_ports [ 30.118096] ahci 0000:02:00.0: forcing PORTS_IMPL to 0x3 I'm attaching an updated patch that fixed the issue for me.
Marius, which kernel version were you using? In later versions, port_map has priority over nr_ports if pop(port_map) <= nr_ports. Can you please try the latest -rc?
Ubuntu's 2.6.24-19-generic (19.34), see bug https://launchpad.net/bugs/244363. I looked at ahci_save_initial_config in Linus's branch (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/ata/ahci.c;hb=HEAD) and thought I saw the same code there. Now looking closer I see the condition is if (map_ports > ahci_nr_ports(cap)) which is different from what I see in the 2.6.24 tree here. In other words, it's my own fault for being inattentive, the fix in the upstream kernel is correct. Would you happen to know when the map_ports consistency check code was changed? I would like to ask my distro to backport this bugfix to their kernel; I assume it would help if I could point them to git commit IDs.
Never mind, found it: 837f5f8fb98d4357d49e9631c9ee2815f3c328ca
Yeah, that one. I had some fun with CAP.NP and PI. :-)
