2.6.3-rc3: radeon blanks screen

2.6.3-rc3: radeon blanks screen

[Alessandro Suardi]

On my Dell Latitude C640 as on Peter Osterlund's laptop - blind-typing
  login/password and startx gets me a visible X desktop.

Old driver with Peter's patch works as before.

Note - this is the same laptop you tried I gave up using framebuffer on
  in the 2.4 series because after 2.4.22-pre4 it would send my screen in
  a crazed-up state (X didn't work either) [that was July 2003].

Please enable the #define DEBUG 1 in radeonfb.h  and send me the
output  again.

OK, here's the debug output part. I'm also attaching gzipped dmesg
  in case you need more context.

Make sure you try with Linus latest bk snapshot as some fixes went
in (along with more debug output) yesterday

Ben.

2.6.3-rc3-bk1 Works For Me (TM).

I can Alt-Fn through consoles, start X, Ctrl-Alt-Fn again to
  a console, back into X. So far, full success :) good work !

Note that there doesn't appear to be any debug difference at
  all compared to the non-bk -rc3:
