I didn't give you enough information, sorry.

What I'm doing is:

fk_at_TP51 ~ $mkdir /tmp/unionfs-src/
fk_at_TP51 ~ $mount_unionfs /tmp/unionfs-src /usr/src
fk_at_TP51 ~ $cd /usr/src
fk_at_TP51 /usr/src $patch -p1 < ~/test/combi.patch
fk_at_TP51 /usr/src $find /tmp/unionfs-src/ -type f
[Panic]

~/test/combi.patch changes about twenty files.

I'm not sure if it's important, but /usr was mounted
readonly and /tmp is a different file system.

My kernel has options WITNESS enabled.

The last step doesn't seem to be the only way to
get a problem, I tried the first four steps again
and umount /usr/src resulted in a reboot.

I was running Xorg and didn't get a panic, but I'll
try again without Xorg, to see if it's the same problem.
