I rebuild my system two days ago with the latest current. When I tried
to print (using lpr) a conf file, the system crashed with a panic in
lockmgr.
I will crash every time I try to print. For the most part the system is
stable, except for lpr.

Here is the dump from the panic and a kernel trace.

panic: lockmgr: pid 439, not exlusive lock holder 322 unlocking
mp_lock = 00000001; cpuid = 0 lapic.id = 00000000

By the way, this is a SMP box with dual PII-400 running on a
SuperMicro P6DBE MB with SCSI disks.

Any suggestions?
