Hi,
I've been getting MCE's repeatedly today when trying to compile 2.5.75-bk1 on 2.5.75-bk1 (obviously I didn't have them yesterday when I build my first 2.5.75-bk1 kernel on a 2.4 kernel).
The MCE is always the same (I think) and reads like this :
CPU 0: Machine Check Exception: 0000000000000004 Bank 0: b600000000000135 at 000000000b99b9f0 Kernel panic: CPU context corrupt
Which when decoded with parsemce gives :
[nim@rousalka parse]$ ./parse -i < mce CPU 0 Status: (4) Machine Check in progress. Restart IP invalid. parsebank(0): b600000000000135 @ b99b9f0 External tag parity error CPU state corrupt. Restart not possible Address in addr register valid Error enabled in control register Error not corrected. Memory heirarchy error Request: Generic error Transaction type : Data Memory/IO : Reserved
I'd like to have some advice on what to do next. Is this a 2.5 bug ? An hardware problem only triggered in 2.5 because it exercises the harware in a different way ? Should I change something in the system ? If so, should I change memory, cpu, psu, something else ?
I don't usually build 2.5 on 2.5, but again yesterday was very hot and hardware might have suffered (the best case cooling can not do much with room temperature = 30+ °C)
Any hint will be welcome - this is my first mce encounter.
