Comment (by bjoe):

 The problem is the linux.ko

 The pc-sysinstall mount all the file systems described in the existing
 fstab. Also linprocfs. Linprocfs provided by linprocfs.ko. This kernel
 modul loaded automatically and depends on linux.ko. This modul loaded
 automatically too. Both loaded in a chroot enviroment from the old
 partition (8.0 PC-BSD) in the new kernel (8.1). When unistalling a linux
 packages the "linux binary/kernel modul execute" and this result in a
 kernel panic.

 A quick solution:
 Befor start the update comment out the "linprocfs" line in /etc/fstab.
 During the update process there some error messages like "ELF binary type
 unknown" on the terminal Alt+F1. After the upgrade activate the
 "linprocfs" line.

 I think there is two options to fix the problem:
 Fix the pc-sysinstall/backend/functions-upgrade.sh. Appends a "-t
 nolinprocfs" on the chroot ${FSMNT} /sbin/mount -a line (Look in the
 Include the linux.ko with linprocfs.ko in the "installer" kernel (here
