Hi everyone!

I have some severe problems on my Athlon X2 system. The problem is that the
system sometimes hangs (during plain web browsing). If I wait long enough the
system comes to a complete halt so that not even sysrq does work. The system
has to be reset and then everything is fine again for some time.

Today I was quick enough to switch from X11 to console and check sysrq output.
After enabling logging (sysrq+6) I got the following messages on console:

ata1: command 0xca timeout, stat 0x50 host_stat 0x4
ata1: status=0x50 { DriveReady SeekComplete }
ata1: command 0xea timeout, stat 0x50 host_stat 0x0
ata1: status=0x50 { DriveReady SeekComplete }

The original error is probably a hardware problem.

Then the system was frozen again and only reset did help. Log files don't
contain any infos which makes sense since ata1 is the disk with the OS and
where metalog should save log files ...

Some infos to my system:

Asus A8V with Athlon X2 3800 and 2GB memory
current kernel 2.6.17 with SMP compiled

I had hoped 2.6.17 would fix this since I seem to remember some fixes for
libata with similar error messages. But at least on my system it did not.

Can you apply the following patch and see what happens?
