Hiho! :-)
I just cvsupped and updated to BETA4.
For the fun of it, I deciced to put WITNESS and INVARIANTS in the
kernel.
When rebooting, I promptly encountered three sucessive LORs and a panic:
panic: _mtx_lock_sleep: recursed on non-recursive mutex bridge @
/usr/src/sys/mo dules/bridge/../../net/bridge.c:940
cpuid = 1
KDB: enter: panic
[thread 100052]
Stopped at kdb_enter+0x30: leave
Trace, LORs, config, etc. are attached to my mail. (sorry for the
mangled output, but I had to use HyperTerminal)
There is no panic at all if I load bridge.ko after the boot process or
if I don't load it at all. I did not yet try what happens if bridge is
compiled into the kernel.
