[issue599] 1.9.0 reproducable panic


From: Peter Avalos <bugs@xxxxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 11 Apr 2007 03:24:26 -0000

New submission from Peter Avalos <pavalos@theshell.com>:

Here's a panic I'm getting with some pretty serious network (www) load, then 
doing a netstat -an:

Unread portion of the kernel message buffer:
panic: m_copydata, negative off -1
mp_lock = 00000000; cpuid = 0; lapic.id = 00000000
boot() called on cpu#0

syncing disks... 5
done
Uptime: 12d22h0m32s

Previous frame inner to this frame (corrupt stack?)

The kernel and vmcore is being uploaded to leaf.  The source is from March 28.
