I replaced the two isp(4) with a dual-channel LSI FC929 mpt(4) card  
on Jan 26 on suggestions that the isp(4) driver could be the cause of  
the memory corruption. Since then, the kernel paniced 3 times but  
always with the same "kernel debugging assertion "ph->ph_nmissing !=  
0" failed". Of the previous 27(!) panics, 2 were also ph- 
 >ph_nmissing != 0 asserts.

The traceback is very similar in the last three panics:
Thu Feb  9 08:01:39 2006
panic: kernel debugging assertion "ph->ph_nmissing != 0" failed: file  
"/u1/netbsd-3.0/src/sys/kern/subr_pool.c", line 1107

cpu1: spinout while in debugger

here the machine locks up hard, no kernel dump.

The last panic was with the change from r1.111 of subr_pool.c  
applied, on the off chance that it was related. See kern/32631: Bad  
concurrency checking can cause a crash in sys/kern/subr_pool.c.

It might be relevant that the kernel is built with LOCKDEBUG and  
DEBUG, in addition to DIAGNOSTIC.

Is this still memory corruption? Or MP related, should I give up and  
go to a uniprocessor kernel?
Any suggestions as to what I could try to narrow down this problem?
