Panic with chromium and 8.1-STABLE (Thu Sep 16 09:52:17 BRT 2010)

[Mario Sergio Fujikawa Ferreira]

Hi,

	I've just began trying chrome web browser from
http://chromium.hybridsource.org/ but it triggered 2 panics on my
8.1-STABLE system.

$ uname -a
FreeBSD exxodus.fedaykin.here 8.1-STABLE FreeBSD 8.1-STABLE #26: Thu Sep 16 09:52:17 BRT 2010     lioux at exxodus:/usr/obj/usr/src/sys/LIOUX  amd64

	The panic information is:

------------
panic: vm_page_unwire: invalid wire count: 0
cpuid = 0
KDB: enter: panic

0xffffff006ecce000: tag ufs, type VREG
    usecount 1, writecount 1, refcount 4 mountedhere 0
    flags ()

    lock type ufs: EXCL by thread 0xffffff00200947c0 (pid 25025)
        ino 119526591, on dev ufs/fsusr

    lock type ufs: EXCL by thread 0xffffff01882cc7c0 (pid 26689)
        ino 263, on dev md0

	I've made available 2 ddb textdumps at:

http://people.freebsd.org/~lioux/panic/2010091900/textdump.tar.0
http://people.freebsd.org/~lioux/panic/2010091900/textdump.tar.1

	I was able to use chrome prior to this latest kernel update.
Now, I can reproduce a kernel panic even browsing www.google.com

	Please, let me know if I can provide any further information.

	Regards,
