Hi,
Since rescent -CURRENT is stable enough, I have the chance to find
out remaining pcm problem. My MP box no more has double fatal fault
and turns into random sleep. The random sleep happens after pcm having
its own problem.
uname -av is
FreeBSD cartier.home 5.0-CURRENT FreeBSD 5.0-CURRENT #1: Wed Dec 4 23:07:36 CST 2002 root@cartier.home:/usr/obj/usr/src/sys/GENERI i386
Kernel config is simply a modified GENERIC, with options SMP,
APIC_IO, and ident GENERI.
Below is what I've got in my dmesg. Complete dmesg is at
