I've been working for a while to try to figure out a problem I'm having
here.
I did a buildworld Sunday, and started to get kernel panics on boot when
it probed fxp. So I removed fxp from my kernel and loaded it as a
module (via loader.conf.local). It paniced. Then I unloaded the
if_fxp.ko on startup, and it booted. But if I load the fxp module now,
after a full boot, everything is great. Rebooting with fxp in the
kernel or loading the module on boot will cause a panic *every* time.
Thinking it might be build problem, I redid the build/install/kernel
again on Monday, and am having the same problems. The panics only
started on the upgrade from a -current dated sometime in early July.
As you will see from below, this is an SMP machine (dual P200) with 256
Megs RAM.
I am also using NETGRAPH to run PPPoE.
Any ideas?
Patrick
The panic is:
