HEADS UP [Re: thread+preemption stability improvement]

[s***@so14k.com]

All,
Initial testing of this patch looks very promising. For those that
aren't comfortable with patching their sources by hand, note that it
was committed to CVS a few hours ago and should be showing up on CVSup
very shortly (rev 1.8 of sys/i386/i386/intr_machdep.c is what you want
if you are running i386). Please go out and test this as much as
possible so that we can determine if futher action is needed.

No luck here. I'm running a GENERIC kernel too. I get a couple of terms
open in XFCE, Gvim, and 4 tabs in firefox and it hard locks.


Regards,
Brad

I just rebuilt my kernel and the problem is back. :-(

I sure hope peter or Scott can figure this out soon. The kernel has now
changed enough that backing off the 4 files I was backing off is no
longer adequate, so I am again running with preemption turned off.

System is P4-M 1.8 GHz UP with SCHED_ULE. It reliably dies on a
buildworld.
