Crash with 2.6.11-mm1-ruby :-(

[Mark H. <Mar...@xs...>]

Hi,


I've been playing with the recent 2611mm1 ruby patch,
to see if I can get my system past the 269 kernel.
Initially I got succes in setting up 2 consoles on fb0 and
fb1 using the new dumbcon=3:4 parameter in combination
with con2fb /dev/fb1 17.
(Thanks Zoltan, Aivils!)

However, after a while not using the second head, it blanked
(I guess because of the screen saver), and when I hit shift to
unblank, it crashed with the following message:

Anyone know what is wrong here? Is there something I can do to fix it?
