Ok -
Just so everyone doesn't think I've vanished from the face
of the earth :-) I thought I'd provide a little status.
I'm now running a 2.1.5-S kernel I grabbed on Oct. 17th.
This kernel has two changes to is:
1) The "patch" Terry suggested to vfs_subr.c
[which, in itself didn't stop my problem from
reoccuring.]
2) The change in vrele() to catch when the usecount
goes negative.
I installed that kernel on Nov. 7th...
It is now Sat Nov 9 14:11:33 EST 1996, and uptime shows:
2:11PM up 2 days, 1:14, 1 user, load averages: 0.81, 0.90, 0.83
That is, the machine has not panic'd since I installed this
kernel.
There is one possibility - perhaps, when I was trying Terry's
suggested patch, I accidently installed the wrong kernel... maybe
Terry's patch does work-around the problem.
There is another possibility - in the past, the machine would
sometimes go for two or three days without a panic. It would rarely
go longer than that. I could be in one of these "lulls."
There is still another possibility, gcc 2.6.3 has a bug which
is tickled by the vrele() code. Changing the source caused the
bad code to not be generated [I'll be the first one to admit
that I'm reaching here...]
Anyway, as soon as something happens, either the typical
panic's I've been getting, or a new panic from usecount<0 in
vrele() - I'll let everyone know...
