Summary: activated KMS leads to complete freeze when viewing BIG images in Iceweasel Product: Drivers Version: 2.5 Kernel Version: 2.6.32-5-686 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: spamfang1199@yahoo.de Regression: No
In early versions of 2.6.32 line, my system used to often freeze when I tried to open big (1,7mb+) images in Iceweasel. Since the kernel got updated, these freezes seem to have vanished.
But now I can reproduce the freeze every time, when visiting a certain .onion site and there viewing a certain picture. Therefore I uploaded this very picture to another pic-hoster and tried to view it there: The machine did NOT freeze. So it is not the fault of the picture itself. It is the teamwork of that specific .onion site and that picture.
This bug occurs NOT, if I deactivate KMS.
When the system is frozen, i can ping it, but not SSH into it any more. Backtraces are very seldom. I only got 4 (see attachment) since the logs usually show nothing.
I have to add another thing:
With activated KMS the desktop always freezes for a few seconds, when opening large pictures in Iceweasel, or clicking on the tab which contains this large picture. It also shows this behaviour, when switching between windows. In earlier versions of 2.6.32 the system often used to freeze completely at that moment. Now its only for a few seconds, except I try the mentioned .onion site with that certain picture.
