Hello,
I'm getting the following messages on my console with a compile from today's (Nov 14,
2003) sources:
Nov 14 19:38:26 syslogd: /var/log/debug.log: No such file or directory

Also, if I don't have debug.witness_ddb=1, I get the following messages:
checking stopevent 2 with the following non-sleepable locks held:
exclusive sleep mutex sigacts r = 0 (0xc1cbdaa8) locked @
/usr/src/sys/kern/kern_synch.c:293
checking stopevent 2 with the following non-sleepable locks held:
exclusive sleep mutex sigacts r = 0 (0xc1cbdaa8) locked @

checking stopevent 2 with the following non-sleepable locks held:
exclusive sleep mutex sigacts r = 0 (0xc1cbdaa8) locked @
/usr/src/sys/kern/subr_trap.c:260
I will also try to buildworld and installworld using the same sources, maybe that will
fix it.
If you need more information please ask.
