Hi folks,

yesterday I upgraded  kernel 2.6.19 to 2.6.20 (gentoo kernel). Now my
box locks up about 10 min after boot.
After that I tested with a vanilla 2.6.21.1 it shows the same behavior.
I'm attaching a kern log file from the 2.6.20. The 2.6.21.1 locked up so
hard, that there was no trace left in the log file.
If I switch back to 2.6.19 everything is fine again.
If necessary I will hook up a laptop to this box, so I can capture
messages via netconsole.

This machine is running an AMD X2 64, NFORCE4 (ASUS A8N-E)

I haven't been following the development of libata for a while, but from
the 2.6.20 changelog It looks like there have been some major changes.

Just let me know what kind of information you need in order to narrow it
down.

Cheers Stefan
