Description Carsten Seibert 2005-08-03 05:54:52 EDT
Description of problem:
When trying to use radeonfb on a Thinkpad T41p (having a "ATI FireGL Mobility T2
(M10) NT (AGP)") and starting X the screen goes blank and the whole system hangs
. Needs to be powered off/on in order to recover.
Just loading the radeonfb module in runlevel 3 works fine and console switches
to higher resolution.
Running the system without radeon framebuffer support works fine.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. init 3
2. modprobe radeonfb
3. init 5
Actual results:
Step 2 shows:
adeonfb: Reference=27.00 MHz (RefDiv=6) Memory=320.00 Mhz, System=202.00 MHz
radeonfb: PLL min 20000 max 35000
Non-DDC laptop panel detected
radeonfb: panel ID string: SXGA+ Single (85MHz)
radeonfb: detected LVDS panel size from BIOS: 1400x1050
radeonfb: Dynamic Clock Power Management enabled
radeonfb: forcefully enabling sleep mode
Console: switching to colour frame buffer device 175x65
radeonfb (0000:01:00.0): ATI Radeon NT

Step 3 causes the system to hang. The Xorg.0.log shows an error in the very last
(EE) RADEON(0): Idle timed out, resetting engine...

Expected results:
X starts and displays login screen.
