Description of problem:
System crashes shortly after boot - lots of disk driver related complaining on the screen - kernel panics - data on drive corropted.
This applies only to AMD Processords running 64 bit version as far as I know. And it may be limited to specific hardware. The problem appears using my Asus Motherboard with the NVidea Chipset. And it only happens with 4 gigs of ram installed. With 2 gigs the problem goes away. I believe it's related mapping memory above the 4gb limit and the 32 bit drivers don't know how to talk to high memory. It might also be Athlon X2 dual core related
The problem has been fixed in the 2.6.13 kernel. I don't know where it is fixed but the new kernel is rock solid. So - the solution to this problem is create a 2.6.13 kernel.
In addition - there is a second bug related to CPU interropt timers that has been discovered and a patch has been created to fix it. The problem is rapid clock advancing - about 10 seconds per minute. It is apparently related to the two processors and lost ticks. This explains it:
And it contains a patch that everyone says works - and it works for me.

So - I'm brain dead right now but a new kernel is needed using 188.8.131.52+ with this patch.
