I just meant that startx (which is root) chmods /dev/console to belong to the user who ran X11. Under a normal text console, /dev/console belongs to root. (So sometimes it would refuse to run and sometimes it wouldn't, and it took a little while to figure out what was wrong.) This is not a problem with your patch applied. > > It does that all the time.

Well, here's the .config, anyway. I don't know where the debug trace is at the moment, so I'll recompile with debug symbols to try to replicate with debug info now. (It happens a LOT for me, on several different machines. Possibly related to using hostfs as root... :) Rob
