Bug#979765: this problem is realted to CPU

[kazimierz01@stodwa.org]

I can confirm, that the bug occurs on HP T5550 only.
On very similar HP T510 it does not - and since both computers share 
same motherboard, it must be the CPU. So the problem occurs only on VIA 
Nano u3500 and does not on VIA Eden X2 U4200.

What other informations can I gather, to help solve this issue?

Thanks,
Kazimierz
