Hi,
I have a SMP machine running FreeBSD 4.3-Release. It has had a kernel
panic every week or so for the last month. I've debugged it as much as I
could using the handbook info, and I believe it may be caused by the
syscall function or in my kernel:
c01e8720 T Xint0x80_syscall
The handbook has helped me get this far, but can someone let me know
what I can do with this now that I know what function is causing the
problem? Thanks.
Matt Rudderham
