 The panic was indroduced on Nov, 10th between 20:00 and 22:00 UTC.
 
 I did track the panic down by doing a lot of cvs updates between Nov 4 and
 Nov 10. Between "10 Nov 2008 20:00 UTC" and "10 Nov 2008 22:00 UTC" and one
 of the following changes cause this panic (the ident diff between this
 two kernels):
 
 -     $NetBSD: ffs_vfsops.c,v 1.239 2008/10/30 17:03:09 joerg Exp $
 +     $NetBSD: ffs_vfsops.c,v 1.240 2008/11/10 20:12:13 joerg Exp $
 -     $NetBSD: ffs_wapbl.c,v 1.6 2008/09/08 03:16:43 joerg Exp $
 +     $NetBSD: ffs_wapbl.c,v 1.7 2008/11/10 20:12:13 joerg Exp $
 -     $NetBSD: vfs_bio.c,v 1.211 2008/11/04 16:08:41 reinoud Exp $
 +     $NetBSD: vfs_bio.c,v 1.212 2008/11/10 21:02:15 joerg Exp $
 -     $NetBSD: vfs_wapbl.c,v 1.3 2008/08/11 02:45:27 yamt Exp $
 +     $NetBSD: vfs_wapbl.c,v 1.5 2008/11/10 20:30:31 joerg Exp $
 
 And these are the files which changed btween 20:00 and 22:00 UTC:
 
 U arch/evbarm/stand/board/nullcom.c
 P arch/evbarm/stand/gzboot/GEMINI_dram_0x01600000/Makefile
 P kern/vfs_bio.c
 P kern/vfs_wapbl.c
 P sys/wapbl.h
 P ufs/ffs/ffs_vfsops.c
 P ufs/ffs/ffs_wapbl.c
 
 where sys/wapbl.h is an additional file which didn't show up in the ident
 output and the arch/evbarm changes are irrelevant since this is a i386
 kernel.
