RE: panic: lock (sleep mutex) vnode interlock on Alpga

[Michael G. Jung]

John/all:

For what it's worth... I started experiencing
this panic problem as described ..

After a make depend and then building/installing
the kernel the problem is gone.

This was from a cvsup ~9:30 EST 9/25/01

Ok, can you try building a new kernel from scratch and see if you still
have
the same problem?  If so, can you back out my latest set of changes to
kern_mutex.c and sys/mutex.h and see if that fixes things?

It looks like witness is somehow getting out of sync.  One cause could
be stale
.o files that aren't being recompiled.  Perhaps you haven't run make
depend in
a while?

APM and PCM compatibility.....

[Michael G. Jung]

All:

On one of my machines at work I run current and had been without "audio"
until
I found a posting where a user noted that enabling "APM" in the kernel
broke audio

Heh... I disabled apm/pmtimer and my PCM device works great While I
don't really care
about APM on my machine - I wanted to note this to "the list".
Possibly this is a BIOS
rev issue ???

The quick facts I can supply are:
