	Hello,

	I have tried your patch. Running kernel runs with ddb.onpanic=1 and 
ddb.commandonenter="mach stack". On new kernel, I have rebuilt all 
NetBSD and started pkg_rolling-replace -u. Load average was between 2 
and 3 and kernel crashes after 50 hours of uptime.

	Kernel doesn't enter in ddb (or try to enter in ddb and aborts with a 
deadlock). On console, I only have :
1 tt=30 tstate=4411001503 tpc=0x1001488 tnpc=0x100148c
2 tt=30 tstate=4482000601 tpc=0x12e1da0 tnpc=0x12e1da4
Stopped in pid 16402.1 (sh) at  1010418:		nop
