Panic in today's current, UFS problem?

I was trying out the new patch from Ville-Pertti Keinonen that might fix my
interrupt storm problems with SATA when I ran into a panic. The dmesg is
attached.

OS: CURRENT, 2004.08.02.16.00.00
    + VIA/SATA patch from Ville-Pertti Keinonen
(http://docs.freebsd.org/cgi/getmsg.cgi?fetch=505643+0+current/freebsd-curre
nt)
    + libdisk patch from Lukas Ertl
(http://docs.freebsd.org/cgi/getmsg.cgi?fetch=526964+0+current/freebsd-curre
nt)


What I did:
1. fdisk/label two 250GB discs hooked up to the on-board SATA controller
(using sysinstall)
2. copy ~20GB of data to both discs
3. successfully run the stress-test mentioned in Ville-Pertti Keinonen's
mail (above)
4. unmount both discs
5. run "atacontrol create RAID0 128 ad20 ad22" (the two SATA discs)
6. fdisk/label the striped array (using sysinstall, forcing it to UFS1)
7. mount the new partition, and create three empty dirs
8. *boom*

The panic:
