Re: radeon crashes with radeonfb - system locked

[drz <drz@rizzux.org>]

OK, now I fixed some things I guess: 

1. yaboot.conf problem:

append="root=/dev/mapper/hda4_crypt video=radeonfb:off radeon.modeset=1"

2. this output still irritates:
# cat /proc/fb
0 radeondrmfb
1 OFfb ATY,Jasper

but doesnt seem to be too much of a problem, because:

# dmesg|grep -e drm -e radeon 
[   29.236109] fb: conflicting fb hw usage radeondrmfb vs OFfb ATY,Jasper - 
removing generic driver
[   29.241882] fb0: radeondrmfb frame buffer device

minor 0
[   63.224028] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id

This last message [   63.224028] seems to be a problem, because if I ssh into 
the machine when it crashed, tail -f /var/log/syslog was giving many many 
errors about ib and framebuffer stuff.

3. Is direct (hardware) rendering enabled, it seems so?

$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI R300 (RV350 4E50) 20090101 PowerPC/Altivec 
TCL DRI2

4. KMS seems to work:

# cat /var/log/Xorg.0.log | grep KMS
(II) [KMS] Kernel modesetting enabled.
(II) RADEON(0): KMS Color Tiling: enabled
