Description Marko Myllynen 2010-04-27 06:33:03 UTC 
Description of problem:
After installing Fedora 13 Beta on a system with Intel display adapter and an old Sun monitor everything worked ok. However, after upgrading to kernel 2.6.33.2-57.fc13.i686.PAE and booting, then while KMS is being enabled the screen goes blank and the monitor displays information "Out of Scan Range".

I'll attach dmesg outputs with both kernels using drm.debug=0x06.

Version-Release number of selected component (if applicable):
2.6.33.2-57.fc13.i686.PAE

How reproducible:
Always
