Description Joachim Frieben 2009-09-07 07:42:13 UTC
Description of problem:
For the current "rawhide" tree, enabling KMS results in a black screen during the boot procedure and in powering the monitor off. The graphics device is an ATI Radeon X800 attached to a 21" CRT HP A4576A.

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

How reproducible:

Steps to Reproduce:
1. Boot system while making sure that KMS is enabled.
Actual results:
Screen turns black and powers off a moment later.

Expected results:
At least progress bar animation is visible as in the "nomodeset" case.

Additional info:
Regression occurred within a week or so.

Once the boot procedure has been completed, X actually starts up as expected.

Comment 2 Chuck Ebbert 2009-09-07 22:31:47 UTC
Can you attach, as plain text, the contents of /var/log/dmesg after booting the problem kernel?

Comment 4 Dave Airlie 2009-10-02 03:28:27 UTC
can we get a boot with drm.debug=0xf?

I think the wierd sync thing is confusing something.
