This is on a Thinkpad T30 (Radeon Mobility 7500), running Fedora Core 6 test 3,
Dual-head mode works but is very unstable, will typically not run for more than
10 or 20 minutes, then we get a hard freeze, I'm attaching xorg.conf file.
A lot of other Fedora users are reporting similar hard lockups, though not
specifically related to dual-head, so this may not be specific to dual-head
support. In my particular case, dual-head makes the freeze happen very quickly.
Built-in LCD support is very stable, even with DRI/Aiglx/Compiz. I've had a few
freezes as well when running an external CRT in 1600x1200 (with the built-in LCD
disabled), but not frequently.
is there any way to obtain more useful debug information when this occurs ? We
hate filing bugs that just say "XXX doesn't work"...

Configuration for dual-head mode
Discussions on reported symptoms and configs :
Please try xf86-video-ati 6.6.3 or current git.
Excellent, xf86-video-ati 6.6.3 seems to fix the problem. Does this make sense
in light of the 6.6.2 to 6.6.3 ChangeLog ? I'll close the bug tomorrow after
some more testing.
6.6.3 seems stable. Closing.
