Hello.
I have been following RELENG_7 and then RELENG_7_0.
I update /usr/src daily and install them.
I think the crash started around 12/18.
Since then, I started seen pancing at umount during shutdown.
I am using GENERIC kernel with SCHED_ULE.
This crash tends to happen after some amount of I/O

Again, I'd have to instrument either the FreeBSD kernel or Squid to

It'd be easy to rewrite it from scratch if IFS were recovered. In

Scott, Adrian:
Even more interesting would be a storage schema for caches that rests
on top of FreeBSD's GEOM facility. One could bypass all filesystems
but still take advantage of the driver architecture.

Hello,
In the last few days I've been experiencing a reproducible kernel panic
whenever plugging in my new digital camera (Pentax Optio Z10). Tried
with a freshly cvsupped system too. I'm using 7.0.
Here is a manual transcript of the panic message, I have some core dumps
too, if needed. They

Mark and Henrik make a number of good points here. Rather than reply
to the details, I'm going to make a couple of quick observations.
As a project we're not leveraging the community sufficiently when it
comes to contributions. The current system of patch review and
submission is very hap-hazard
