Description Ulrich Drepper 2005-08-16 22:04:26 EDT
Description of problem:
The current rawhide initscripts load the radeonfb kernel module on my T42
laptop.  After that happened starting the X server locks up the machine.  I
suspect it happens when loading the libxaa.a module.  I guess this is the case
from the logs but I cannot be sure, no other information is stored.

Version-Release number of selected component (if applicable):
... and probably many more

How reproducible:

Steps to Reproduce:
1.get t42 model 2378R2U
2.start up, make sure radeonfb is loaded
3.start X
Actual results:

Expected results:
X starts

What does work is to add radeonfb to the hotplug blacklist and then manually
load the radeonfb driver after X is up.  This will disturb the picture, but a
quick switch to the text console and back restores it.

Once the module is loaded I can suspend the machine and on wakeup the display
works as expected.  Without the module loaded the display doesn't come up correctly.

is this still happening with latest kernels ?
