I read through the thread Robert initiated with CF on PCMCIA and noted with interest that the issue seemed to be related in the end to lost interrupts. However the compact flash I'm using is an IDE/PATA device connected directly to the motherboard with no intermediate devices such as PCMCIA. As the issue is unlikely to be the same but maybe similar I followed the same path, applying the patches that Tejun issued to 2.6.22rc6 to provide more debug information in the hope that someone can help me identify this issue. I have applied 2.6.22rc6 + timing-debug.patch + disable-dev_init_params.patch as per: http://marc.info/?l=linux-kernel&m=117966084223982&w=2 Here is the relevant output from dmesg: Linux version 2.6.22-rc6 (root@localhost) (gcc version 4.1.1 20070105 (Red Hat 4 .1.1-51)) #3 SMP Wed Jun 27 14:25:12 EST 2007 ... ata_piix 0000:00:1f.2: MAP [ P0 P2 P1 P3 ] ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (level, low) -> IRQ 19 scsi0 : ata_piix scsi1 : ata_piix ata1: SATA max UDMA/133 cmd 0x0001fa00 ctl 0x0001f902 bmdma 0x0001f600 irq 0 ata2: SATA max UDMA/133 cmd 0x0001f800 ctl 0x0001f702 bmdma 0x0001f608 irq 0 ata1: soft resetting port ata1: reset complete ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: ATA-0: CF CARD 512MB, 20070131, max MWDMA2 ata1.00: 990864 sectors, multi 0: LBA ata1.00: applying bridge limits ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: configured for MWDMA2 ata1: EH complete ata2: soft resetting port ata2: reset complete ATA: abnormal status 0x7F on port 0x0001f807 ata2: EH complete scsi 0:0:0:0: Direct-Access ATA CF CARD 512MB 2007 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 990864 512-byte hardware sectors (507 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DP O or FUA sd 0:0:0:0: [sda] 990864 512-byte hardware sectors (507 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DP O or FUA sda:<3>ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 cdb 0x0 data 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1: port is slow to respond, please be patient (Status 0xd0) ata1: device not ready (errno=-16), forcing hardreset ata1: BUG: prereset() requested invalid reset type ata1: soft resetting port ata1: reset complete ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: model number mismatch 'CF CARD 512MB' != '' ata1.00: revalidation failed (errno=-19) ata1.00: limiting speed to MWDMA2:PIO3 ata1: failed to recover some devices, retrying in 5 secs ata1: soft resetting port ata1: reset complete ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: model number mismatch 'CF CARD 512MB' != '' ata1.00: revalidation failed (errno=-19) ata1.00: disabled ata1: soft resetting port ata1: reset complete ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: ATA-0: , , max PIO0 ata1.00: 0 sectors, multi 0, CHS 0/0/0 ata1.00: applying bridge limits ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: model number mismatch '' != 'CF CARD 512MB' ata1.00: revalidation failed (errno=-19) ata1: failed to recover some devices, retrying in 5 secs ata1: soft resetting port ata1: reset complete ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: issuing IDENTIFY ata1.00: IDENTIFY complete ata1.00: configured for PIO0 ata1: EH complete divide error: 0000 [#1] SMP CPU: 1 EIP: 0060:[<c03c7a48>] Not tainted VLI EFLAGS: 00010046 (2.6.22-rc6 #3) EIP is at ata_build_rw_tf+0x20e/0x275 eax: 00000000 ebx: 00000000 ecx: 00000000 edx: 00000000 esi: c2134a40 edi: 00000000 ebp: 00000000 esp: f7c4be94 ds: 007b es: 007b fs: 00d8 gs: 0000 ss: 0068 Process scsi_eh_0 (pid: 972, ti=f7c4a000 task=f7867070 task.ti=f7c4a000) Stack: 00000000 c2134188 00000000 00000000 f7c42bc0 c2134188 c2134a30 c03c8a86 00000000 00000000 00000008 00000000 00000000 00000000 c20fb140 f7c42bc0 00000000 f7c3bb58 00000000 00000000 00000008 c2134a30 f7c42bc0 c2134188 Call Trace: [<c03c8a86>] ata_scsi_rw_xlat+0x13d/0x1f8 [<c030b815>] scsi_done+0x0/0x16 [<c03c8c57>] ata_scsi_translate+0xf0/0x156 [<c01215e8>] lock_timer_base+0x19/0x35 [<c030b815>] scsi_done+0x0/0x16 [<c03cad64>] ata_scsi_queuecmd+0x10f/0x12c [<c03c8949>] ata_scsi_rw_xlat+0x0/0x1f8 [<c030bb44>] scsi_dispatch_cmd+0x185/0x1c9 [<c030fdc4>] scsi_request_fn+0x20d/0x2c2 [<c021fcf8>] blk_remove_plug+0x4f/0x5b [<c0220064>] blk_run_queue+0x37/0x63 [<c030f46f>] scsi_run_host_queues+0x10/0x22 [<c030e4bd>] scsi_error_handler+0x237/0x26f [<c0114d80>] complete+0x39/0x48 [<c030e286>] scsi_error_handler+0x0/0x26f [<c01292f3>] kthread+0x38/0x5d [<c01292bb>] kthread+0x0/0x5d [<c0103153>] kernel_thread_helper+0x7/0x10 ======================= Code: 0f 77 7b 81 7c 24 28 00 01 00 00 77 71 8b 54 24 04 89 f0 e8 f1 a2 ff ff 85 c0 78 69 8b 54 24 04 89 f8 0f b7 8a 40 02 00 00 31 d2 <f7> f1 89 04 24 8b 44 24 04 89 d1 31 d2 0f b7 98 3e 02 00 00 8b EIP: [<c03c7a48>] ata_build_rw_tf+0x20e/0x275 SS:ESP 0068:f7c4be94 - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
