All,
I just compiled 2.4.2 and installed it on a otherwise stock
Redhat 7.0 platform. The system is a SuperMicro PIIISME,
running dual PIII 750s, with 256 cache. It appears that about
every 10 to 18 hours, the system is panicing, and freezing
up. The first time, I got an oops 0000, the second time an
oops 0002. Both crashes have occured only when the systems is
at 100% cpu utlization; processing several hundred MRTG
indexmaker operations.
I ran ksymoops on both outputs, and the results are pasted
below. Note, I compiled the kernel without loadable module
support. Please let me know if there is anything else I can
do/provide to help. Unfortunately, the second didn't output
enough for ksymoops to extract anything usefull.
v/r
