Bug Description

Upon startup, my Seagate SATA 80GB harddrive is not detected. I get:

BUG: at drivers/ata/libata-core.c:4374 ata_hsm_move()
...

in my dmesg. My motherboard is an Asus A7N8X-Deluxe, and I am running Feisty with Linux 2.6.20-5-386. The drive was detected in Edgy.

Is this Feisty from the Herd 2 media?

Edgy + kernel image in feisty?
kernel of www.kernel.org or package of feisty?

I currently have 2.6.20-8-386 running with fully updated feisty packages as of yesterday 2007-02-17. I upgraded from Edgy by changing all my repos from Edgy to Feisty and using apt-get dist-upgrade.

I was browsing the changelog for 2.6.21-rc2:
http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.21-rc2,
and saw a possible fix for this issue. Commit: e2f8fb72144a9f38d44ccf3f939e939392eda659
 says:
"sata_sil: ignore and clear spurious IRQs while executing commands by polling

    sata_sil used to trigger HSM error if IRQ occurs during polling
    command. This didn't matter because polling wasn't used in sata_sil.
    However, as of 2.6.20, all IDENTIFYs are performed by polling and
    device detection sometimes fails due to spurious IRQ. This patch
    makes sata_sil ignore and clear spurious IRQ while executing commands
    by polling."

I haven't tried this new kernel, but could if that is necessary.

I applied the fix included in the patch above, and the problem was solved. I was able to mount my SATA drive with no problems.
