Bug#401035: Workaround for this ST340823A drive or kernel bug?

[Mikko Rapeli]

One workaround found: use vanilla 2.6.22.1 which defaults to
libata. I also unset EFI_PARTITION with 2.6.22.1, but I don't think that 
solved it. 

In my case, when disk content was already under lvm, only grub option for 
root filesystem needed a change from /dev/hda2 to /dev/sda2.

Are pata and libata usable with etch kernels? If so, how to switch from
ide-disk to pata?

I think bug #421870 is about the same issue too.

Bug#401035: Workaround for this ST340823A drive or kernel bug?

[Mikko Rapeli]

Hello,

I just hit this bug too. The drive has been working without errors on 
sarge kernels for a couple of years and a badblocks read only test just 
finished without errors (non-destruct. write test ongoing, fsck's for 
the filesystems report no errors), so this is 
very likely not a defective IDE drive. Kernel 2.6.8-16sarge7
reports the drive as:

hdd: ST340823A, ATA DISK drive
ide1 at 0x170-0x177,0x376 on irq 15
hdd: max request size: 128KiB
hdd: Host Protected Area detected.
current capacity is 78165360 sectors (40020 MB)
native  capacity is 78165361 sectors (40020 MB)
hdd: 78165360 sectors (40020 MB) w/1024KiB Cache, CHS=65535/16/63, 
UDMA(33)

With 2.6.18.dfsg.1-12etch2 I get tons of similar errors early at boot 
and can't stop the screen. I think the seek fail messages are there and 
all I get to syslog on another drive is:

Jul 25 18:07:29 nalle kernel: end_request: I/O error, dev hdd, sector 0
Jul 25 18:07:29 nalle kernel: printk: 897 messages suppressed.

Jul 25 18:07:29 nalle kernel: end_request: I/O error, dev hdd, sector 0

Jul 25 18:07:29 nalle kernel: end_request: I/O error, dev hdd, sector 51809625

I see this has been reported here and there ( 
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/26119 
), but has anyone seen even a workaround for this?
