Description Ellen Shull 2009-03-17 04:14:43 UTC 
Version:           kdebase-workspace-4.2.1-7.fc10.x86_64 (using KDE 4.2.1)
Compiler:          gcc 4.3.2 x86_64 (I believe, that's f10 current) 
OS:                Linux
Installed from:    Fedora RPMs

(original report at
https://bugzilla.redhat.com/show_bug.cgi?id=484606
RH peeps said to push upstream)

Ever since the initial release of 4.2, up through the current 4.2.1, I've experienced intermittent plasma crashes that I did *not* suffer in < 4.2.  Unfortunately I haven't been able to come up with a way to reproduce these on demand, but they happen often enough that I've got a pile of 15 kcrash reports saved now.

Have experienced on various kernels from at latest 2.6.27.12 up to current 2.6.29-rc8-git2.

Happened both on my prior 7950GT and current 8800GT using 180.29 nvidia drivers.  Monitor is 2560x1600, compositing fully enabled.

selinux and all other default Fedora security paranoia enabled.

Created attachment 32176 [details]
last backtrace I got on 4.2.0 before moving to 4.2.1

Also see the three attached to the original RHBZ report.  I can attach my whole collection of these if they're useful.
Comment 3 Kevin Kofler 2009-03-17 06:52:36 UTC 
Note that the reporter says in the Fedora bug that this also happens on Intel graphics hardware, so it doesn't sound like a driver bug.
