Please make sure you have

Hum, remind me of what I did see on the old ftp.fr.netbsd.org:
any significant I/O with a SMP kernel while parity rebuild was running
would cause a hang. Using a UP kernel for parity rebuilds and switching
back to MP after a clean reboot would make the system work.
This was on i386 though, and with SCSI disks. I've never been able to
reproduce it on another system.
Anyway please make sure you have sys/dev/raidframe/rf_netbsdkintf.c 18.104.22.168
it may help ...
