I made new kernel, but it doesn't work well.  It looks like
kernel diagnostic routines found deadlock or something, but
I'm not sure.  Where should I start to look over?  Thanks.

My configuration file is:

  include "arch/i386/conf/GENERIC.MPDEBUG"
  options 	NMBCLUSTERS=1024
  options 	GATEWAY		# packet forwarding
  pseudo-device	raid		4	# RAIDframe disk driver
  options 	RAID_AUTOCONFIG		# auto-configuration of RAID components

And console shows
