Description Roman Jarosz 2012-08-04 09:27:50 UTC 
Hi,

using latest git source 036b90f099af21e60fb4c3684616daf1927f705e i can easily reproduce a GPU hung while watching video in VLC using SNA acceleration (UXA is ok). Display goes black, audio still plays, keyboard works.

Steps to reproduce:
With SNA start video in VLC
Let it play on external display connected to VGA port. (maybe not important, will test)
After a while the screen goes black.

Using KDE without composition.

I should have debug info in intel driver, but somehow it isn't in the log

    One flush removal too many, keep those fingers crossed that the others
    do not make an unwanted return.
