2.6.28-3.9-rt fails to boot correctly (screen issue?)

[Sébastien Valette]

Hi,
on my Sony VAIO NS12M, the -rt kernel fails to boot, giving me a garbled screen and no interaction. Trying to switch consoles gives me a reboot. I join the full kernel log. Maybe this is interesting:

@Sébastien,

Let me guess do you have an ATI video card?
Thanks!

Ciao,
Alessio

[Sébastien Valette (sebastien-valette)]

Indeed, I have an ATI videocard. I tried fglrx,radeon and vesa drivers, all fail....
