I didn't give you enough information, sorry. What I'm doing is: fk@TP51 ~ $mkdir /tmp/unionfs-src/ fk@TP51 ~ $mount_unionfs /tmp/unionfs-src /usr/src fk@TP51 ~ $cd /usr/src fk@TP51 /usr/src $patch -p1 < ~/test/combi.patch fk@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.
