Hi, 

i tried V0.7.7 and since all other RP kernels locked for me in X, i decided
to go to the console and try to see if i get some debugging output. Well i
put the usual stress on the system but besides some higher rtc_wakeup
jitters [up to 60%] which didn't show during the earlier runs that locked
when in X, the system ran fine. i wasn't able to lock the system from within
the console (X was started but idling at gdm).

Ok, so i suspected, maybe the locks i see got to do with X, so i changed to
the X console, logged in and quicklky switched back to the console. and no
surprise 10seconds later or so it locked (i suppose gnome was still loading
at that point in time). Without any console output. Does it matter which
virtual text console one is on? i thought not.

anyways. i might just get myself a serial console in a few days (old pc
froma buddy). but i thought a serial console would be mostly useful to
capture more of the debug messages. if none shows at all it won't help
either right?
