Dan and List,

We're in the process of moving our web and mail servers over to ydl - it's
taken far too long and we've run into a few problems here and there. The one
that really scares us is the kernel panics when:

1. Quota Support is Turned on in the Kernel and it's enabled and running.
2. Changing a user's password.

These kernel panics have happened multiple times on multiple machines last
night.

We were in the process of moving things over and recreating users (changing
their passwords in the process) when this all started.

Quota alone has been a problem, we've had to turn it off completely as this
is the startup messages that we've been getting on startup. We've left it
for half and hour and it still didn't start up. There's only 6GB of drive
space and most of that is unused right now, there just aren't that many
files to check:

It goes on for pages and pages before it ends. Then there are the kernel
panics Here's the logs from one of them:

Jul 18 00:32:23 mulder kernel: Kernel panic: kernel access of bad area pc
c0051108 lr c0051648 address 40000004 tsk pidof/2275

Since then, we've turned off quota on those 2 machines (the only 2 servers
that we're running ydl on) and we've had no kernel panics at all.

Anyone got any ideas? I'm at a loss and am a little scared of quota support
- we need the functionality but I don't want to be holding my breath every
time I have to reset a password.

Thanks.
