Gang,

The following change broke KSE on ia64:

--------
revision 1.18
date: 2003/11/08 06:07:04;  author: davidxu;  state: Exp;  lines: +16 -17
Use THR lock instead of KSE lock to avoid scheduler be blocked in spinlock.
 
Reviewed by: deischen
--------

We seem to be clobbering the thread structure instead of writing
to the mailbox. This happens at initialization. Can it be that
the change assumes PER_KSE and doesxn't work for PER_THREAD?
