Panic on 7.0-STABLE during fsck(1) on UFS2

Hi,

	I got a panic on a ASUS M2N32SLI Deluxe (AMD Athlon 64 X2
Dual Core Processor 4600+) running i386 7-STABLE as of December,
27th.

FreeBSD exxodus.fedaykin.here 7.0-PRERELEASE FreeBSD 7.0-PRERELEASE #29: Thu Dec 27 08:23:15 BRST 2007     lioux_at_exxodus:/usr/obj/usr/src/sys/LIOUX  i386

	The panic happened on a page fault during a fsck(1) operation
on a UFS2 filesystem. No zfs on this system. Swap is untouched.

        Further information is attached. Let me know if there is
anything I can do to help.

	Regards,

ps: To uncompress the lzma compressed files, proceed as following

# cd /usr/ports/archivers/lzma
# make install clean
# lzma d vmcore.1.lzma vmcore.1
# lzma d kernel.debug.lzma kernel.debug

so that you can access vmcore.1 and kernel.debug
