Dear Linux folks,

using Debian Sid/unstable, clicking on a mail address in Iceweasel (Firefox) a composer window is opened in Evolution 3.4.3-1. But then the windows are only gray and hang and the only way to fix this is to kill the process. I reported this issue to the GNOME Bugzilla as 685640 and the developer Matthew Barnes pointed out the following [1].

--- Comment #1 from Matthew Barnes mbarnes@redhat.com 2012-10-07 11:59:35 UTC --- Radeon video driver thread looks stuck:

Thread 5 (Thread 0x7f6656d4d700 (LWP 4375)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 No locals. #1 0x00007f6656f4c9f3 in pipe_semaphore_wait (sema=0x7f666b6577b8) at ../../../../../src/gallium/auxiliary/os/os_thread.h:432 No locals. #2 radeon_drm_cs_emit_ioctl (param=0x7f666b635c40) at radeon_drm_cs.c:401 cs = 0x7f666b635c40

Any hints how to fix this are much appreciated. If it is indeed a Linux issue, I will gladly create a new ticket in the freedesktop.org Bugzilla.

Thanks,

Paul
