next in thread | raw e-mail | index | archive | help
Hi,
On my Athlon XP 1800 / Abit KX7-333R system, I've been encountering
intermittent kernel panics during periods of high disk activity or when
running cvsup or make buildworld.
What's notable is that at this point the motherboard, CPU, and power
supply have been replaced and the system has no difficulties running
Memtest86 for several hours. Additionally, this problem does not happen
EACH time I generate a lot of disk load or run cvsup, but occasionally.
Per the handbook, I've built a debug kernel and captured crash data.
Below are my dmesg, and the output of several kgdb, list *instruction
pointer and backtrace.
What are some of the next steps I can take to help resolve this or find
the cause of these crashes?
Any help is highly appreciated. Please CC me when responding as I am
not subscribed to this list.
Thank you,
Anthony Volodkin
