Xorg crashed with SIGABRT in FlushAllOutput()

[Dominic Laumer]

Hi guys,

Yesterday I upgraded my Kubuntu Vivid computer to Wily, after rebooting X started to crash completely randomly (or at least it seems so) after about 10-30 minutes of normal use (even while trying to report this using the Apport GUI). Used graphics hardware is the AMD Radeon HD6550D with the open source driver.
