Hi! Sorry for sketchiness in this report, but the xen domain0 kernel (I don''t have any guests set-up yet) just shitted all over /etc directory and locked up the machine while trying to do shutdown. There was a backtrace or somesuch on the screen, but apparently that was not logged anywhere. On next boot, the xen kernel halted while trying to fsck, so I gave up and started the standard kernel and then fsck.ext3 corrected a few thousand errors (or so it seemed) on the / partition. The problems happened on the first and only boot to the xen kernel ever, about 20 minutes after installing FC5. The machine is a bog-standard dell optiplex gx620 (P4 HT), with 3G memory. Did I hit a known bug? I''m not on the list, so please keep me on cc ... Taneli
