[PROBLEM] kernel BUG at include/linux/blkdev.h:601

[Srihari Vijayaraghavan]

Vanilla 2.6.12 or 2.6.12-git* (the below BUG/Panic
report is from 2.6.12-git9).

Hardware:
ICH4: chipset revision 1
ICH4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0x1860-0x1867, BIOS settings:
hda:DMA, hdb:pio
    ide1: BM-DMA at 0x1868-0x186f, BIOS settings:
hdc:DMA, hdd:DMA
hda: IC35L060AVV207-0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdc: LITE-ON LTR-48246S, ATAPI CD/DVD-ROM drive
hdd: HL-DT-ST CD-ROM GCR-8482B, ATAPI CD/DVD-ROM drive

Software:
Linux-2.6.*
Vanilla FC4 + official updates

How to reproduce:
Insert Coldplay X&Y CD album (yes, it's a
copy-controlled cd), and wait for few minutes until it
crashes. No need to even 'play' it.

end_request: I/O error, dev hdc, sector 0

Buffer I/O error on device hdc, logical block 0
hdc: command error: status=0x51 { DriveReady

[Sorry for replying to my own email]

2.6.13-rc1 (plus Hugh's get_request patch) doesn't
suffer from this problem, unlike 2.6.12 and 2.6.12-git
releases.

That's a little strange, as there should be no changes in this area so
far. Are you 100% sure?

Absolutely. 2.6.12 and 2.6.12-git9 crash within
minutes/seconds; OTOH, 2.6.13-rc1 (plus Hugh's patch)
survives this torture test for hours (despite
generating 30+ MB of kernel/IDE error messages :). No
OOPS, no BUGs, no panics, just truck load of error
messages.

I haven't tested whether earlier releases of 2.6
suffer from this (such as 2.6.10, 2.6.11 ..) or other
hardware combinations exhibit the same problem etc.
Tell me, if you want me to.

Thanks
Hari

There are some minor ide updates outside of ide-cd, they must be
accounting for your success in 2.6.13-rc1 then. Could you test 2.6.12
with this patch applied?

Actually, I've tested it on another computer (AMD64):
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on
pci0000:00:0f.1
    ide0: BM-DMA at 0xcc00-0xcc07, BIOS settings:

hdd: RICOH CD-R/RW MP7083A, ATAPI CD/DVD-ROM drive

Unfortunately, there's still problem with that patch
with Ricoh drive:

Kernel panic - not syncing: Aiee, killing interrupt
handler!

With 2.6.13-rc1 (+Hugh's patch), all is well in this
computer. And oh, the LG DVD-RW drive doesn't crash
even in 2.6.12, though I didn't wait for more than 10+
minutes. (IOW, it must be hardware dependant.)

Thanks
Hari.

PS: I added -ide suffix to kernel version, so that
kernel build doesn't overwrite the real 2.6.12 modules
directory.
