Description arousch 1999-11-06 22:10:00 UTC
While running 'make world' and TOP the following fatal error stopped the system:
------------
panic: lockmgr: locking against myself
mp_lock = 01000001; cpuid = 1; lapic.id = 00000000
boot() called on cpu#1

syncing disks... 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 giving up

Automatic reboot in 15 seconds
------------------
This is on a system running an SMP kernel with dual pentium pro 200's and 96MB of ram.

Fix: 

no known fix
How-To-Repeat: This error occured when:
1. A 'make world &' was running
2. 'top' was running as root to the console
3. user secure shelled into the system 'su'ed' and ran 'top' to his screen.

At such time the system got upset.

State Changed
From-To: open->closed


A lot has changed since 3.3, so I assume whatever caused this has 
been fixed. At the minimum, some sort of stack trace would be 
needed to debug this further.
