Summary: [KMS] KDE 4.3 causes lock up on RV620 (M82)
Product: DRI
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: zaj...@gmail.com
First I reported but #24467 but it was incorrect.
I was successfully using openSUSE 11.1 (KDE 3.5.x) with KMS. Probably about 30
KDE 3.5 sessions without any lock up. Then I switched to openSUSE 11.2
milestone 6 (KDE 4.3.0) and run *one* KMS X session, it was fine. Next switched
to 11.2 milestone 8 and experienced lock up.
First I thought it was due to regressions in drm/radeon and even tried to trace
it in bug #24467. But that was just matter of (un)luck. One KDE 4.3 sessions
for 20 tries works fine. I even reinstalled milestone 6 and confirmed it's
freezes. Also tried going back to commits tested with openSUSE 11.1 and no luck
here.
So finally, it seems KDE 4.3 (both .0 and .1) do some operation that locks up
my machine. This is not likely to be Mesa's r600 related, as I removed this
driver.
Also I've tried starting plain X, playing movie with mplayer in it, starting
"konsole" (KDE4's app), xclock and xeyes. It was working fine, no lock up. Then
I started "kwin" (KDE4's window manager/decorator) and that causes lock up
seconds after starting it.
