And the HDD is absolutely OK. There are some flaws with the motherboard or some other core components other t

I'd like to give a feedback regarding the crashes I've reported. I transferred my system to my spare laptop (exactly the same model). I haven't experienced any hangups or file systems problems so far, using the same kernel (hardened-sources-2.6.36-r7) and performing the same tasks - including a reg

I see. Now I fired up my spare notebook and transferred the system in the mean time. :P I'm currently suffering of crashes occuring while I'm transcoding a scientific event's DVD content. It became very frustrating. Would it be possible that the CPU itself is actually failing (opcode )? The t

No errors were found after 12 hours of memtest. However some serious crashes still occur. I attach snippets of kern.log. Is it still suggests a hardware error? I have to try out another laptop. That is not convenient... Dw. -- dr Tóth Attila, Radiológus, 06-20-825-8057 Attila Toth MD, Radiolo

There were two screen shots attached. The older one was outdated related to 2.6.32 kernel. But the other was a recent panic. So here is another one. This time I could paste it from the log: last sysfs file: /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:00/PNP0C09:00/PNP0C0A:00/power_sup
