1.149 is ok but 1.150 is perhaps bad.  Here's where I am at the moment:

D2008.07.15.06.00.00 is OK
D2008.07.16.06.00.00 errors with page fault in the boot (Murphy strikes 
again :-)
D2008.07.16.18.00.00 is bad

One time related commit in relevant interval is

http://mail-index.netbsd.org/source-changes/2008/07/15/msg207834.html

which, among other things, changes the type of ptimer.pt_time from itimerval 
to itimerspec (itimerval is the argument type to setitimer).  It is, however 
not clear to me that this change is significant since the struct sizes are 
the same.

I'll try to narrow it further.
