  I've been running NetBSD 4.0_BETA on a 5000/150 for some time, and 
wanted to update to NetBSD-5.0_STABLE so I could get WAPBL and RaidFrame 
parity map [a 6GB raid5 volumne takes quite a while to rewrite parity].
I've been able to boot a kernel, but have problems going to multiuser.
It's a mail machine and runs clamd, which takes more and more memory.
It kind of looks like possibly a problem in bt_insbusy() called from 
vmem_xalloc() when memory gets tight.  I haven't had much time to try
to debug this yet (the RaidFrame parity really hurts here).  I also
tried a NetBSD-4.0_STABLE kernel, with the same results.  I noticed there 
were a number of changes in subr_vmem.c between my 4.0_BETA and 
4.0_STABLE.
