[Bug 37382] Re: ata timeout freezes system partly

[StiffMe]

my kernel is 2.6.20-15-generic
my laptop works fine on edgy and dapper.
when i use feisty, my system freezes from time to time. Every time it freezes, I have to wait for about half a minute, and then it works fine again.
Then i enter a console , and kernel showed the following output:
ata1: failed to respond(30 secs, status 0xd0)


sometimes kernel showed :
ata1.01:exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
ata1:01cmd a0/01:00:00:00:00/00:00:00:00:00/b0 tag 0 cdb 0x43 data 12 in


I have a PATA harddisk ,but in feisty, my hard disk is recognized as /dev/sda
I tried to compile kernel source of version 2.6.20 from kernel.org, this problem remains.

PS: I am using ICH7, in feisty, at first ,no sound is out. But actually
kernel detects my sound card and is LOOKS fine. The Only problem is NO
sound out. Then i compiled the alsa driver and lib from alsa website,
and the problem is resolved.

Sorry for my English.I am not good at it.
