Re: Bad page state on AMD Opteron Dual System with kernel 2.6.13-rc6-git13

Hello all together, 

for now i can confirm, that the problem disappears!

I have done the following:

First try the msr fix, this doesn't solve the problem entirely, but
there were no kernel panics.

With the randomize_va_space setting the general protection disappeared
too ...

I'm now happy and will go for holiday ( 4 weeks *g*). After that i will look
if the machine gets some problems back, but i don't think ...

I thank you all for your help!

Every time I think I know where it's at, they move it.
