funny kernel death with ksoftirqd_CPUX taking up almost 100% of cpu?

[Kevin B. Hendricks]

Well,

I still have to debug that damn OOo 1.0.1 bridge problem so I have to go
back into OOo and gdb (which uses alot of memory) and try again.

If I run into it again, I will let you know.

If so, is there anything debug wise I can do that would help pinpoint the
problem.

Thanks,

Kevin
