Having used 3 different versions of Catalyst including Catalyst 13.4 I keep periodically getting freezes of the desktop when either running OpenGL Apps or playing Video or both. When I say freeze I mean that the entire desktop including mouse pointer stops! However you can ssh into the box and do whatever including rebooting to restore operation.

It sounds like others in the community are also seeing this with no explanation. In my case every freeze I have seen (about 30 over the past year on 3 different computers) has been related to what appears to be a bug in the fglrx heap manager. Every time I get the identical information to what I post below in the /var/log/messages file.

I googled this and others have reporting seeing it too. I however do not see any recent references on this forum. I want to report it to AMD but it appears they only want reproducible problems and I have no consistent way to reproduce it YET the problem certainly occurs though usually at the worst times.

It seems like apps that use lots of of large textures trigger it more readily as does multiple OpenGL using apps like OpenGL Desktop effects, an OpenGL game, and OpenGL video running all at the same time. However the problem has occurred in simple scenarios also. Sometimes I will go for weeks without seeing it and other times it will bear its ugly head 3 times in a week all under similar usage.

My question to the community is are others seeing this? Does anyone have a scenario that frequently and consistently causes this? as this could be documented as the way to reproduce.

For anyone seeing this post who has periodic desktop freezes please check your /var/log/messages file or archived messages files for a similar trap report to what I have posted below.

I feel that most random non hardware related desktop freezes (at least with Radeon 7000 hardware) are related to this one bug and it would benefit all us users and AMD to get this Gremlin tracked down and fixed.

The hardware of all 3 of my systems is AMD Dual Opteron 43XX or FX8350 CPU's, 32GB of ECC memory, and either Radeon 7750 or 7770 Graphics boards. The systems are other than this issue absolutely stable.

The Catalyst I currently have installed is under OpenSuse 12.3 and from http://geeko.ioda.net/mirror/amd-fgl...4-3.x86_64.rpm download which is Catalyst 13.4 put into an easy to install RPM. I have however seen this with prior Catalysts and ones installed from the AMD downloads.

Here is the dump I get in /var/log/messages:
