However, the system won't boot anymore. :-( The bootloader still appears, grabs kernel and modules, followed by Can't work out which disk we are booting from. Guessed BIOS device 0xffffffff not found by probes, defaulting to disk0: panic: free: guard1 fail @ 0x6c23c from /usr/src/sys/boot/i386/loader/../../common/module.c:959 press any key to reboot Maybe I did something stupid during the update, though I cannot imagine what it might have been. Any hints how to get my system back online? cu Gerrit
