Netware 6.5 SP5

Twice today I've gotten the following error, unfortunately it's not
getting caught in the abend.log

I just turned off auto restart after abend, but I'm seeing this in the
HP Proliant Integrated Management Log

Abnormal Program Termination (Abend: Kernel detected an attempted contex
switch when it was not allowed Running Process: Server 27 EIP: 21B688h)

That occurs right after

Fatal Exception (Number 14, Cause Abend: Page Fault Running Process:
Server 27 Code executing in module LSIMPTNW.HAM v4.0e at offset +20CB9h)

So it appears for some reason the scsi controller is abending. What's
odd is that abend.log only records abend 2? Why wouldn't it record the
first one first?
