Hello!


I found to references regarding this problem in this list. Many Maxwell
reported this and Tejo asked if his supposed fix helps out. 

Another reference by Jeff suggests bisecting a git commit. Since I am
very unexperienced in the git stuff I hope it is okay to start another
initial mail about this to ask

1.) What I should try out on the code to trace this further down

2.) I would extend this problem on >2.6.25 version of kernel.

I have an "nForce3 250 chipset" on an Asrock K8Upgrade-NF3 Motherboard

While 2.6.25 works very fine I experienced this with 2.6.26_rc7 at first 
(I skipped versions between). Cold Boot yields into the described error,
I sadly only have real screenshots of this:

http://ludenkalle.de/sata

After a reset the Kernel was not able to do anything useful with the
SATA interface anymore (this description is a bit vague, IIRC it stuck
immediately around "SATA Link down..."). Only powercycling helped out,
then it booted with SATA.

Now I have 2.6.27-rc3, same error but config netconsole enabled.

Hmn, thats it. Where should I poke into?

Kind Regards, Konsti
