>Description:
Hardware has been tested and works well with NetBSD 1.3.2.
Upgraded to 1.4. Upgrade scripts failed, so I did a clean install.
Noticed that I couldn't print. 
Did a "cat /etc/printcap>/dev/lpt0" and got this error:

panic: lockmgr: pid 338, not exclusive lock holder 16777215 unblocking
stopped in cat at _Debugger+0x4: leave

Dropped me in kernel debugger. I did a "continue" and got this:

synching disks: panic lockmgr: using decomissioned lock

I am using a custom kernel, which I have. I also have a crash dump.
