Hi Jerome, after application of all of your 3 patches, I got GPU softresets in log from time to time and sometimes also hard locks. Is there a way how to capture the faulty command to log? How to turn on some debug logging? I use Mobility Radeon HD3450. And the GPU lockups occur mostly during window manipulation in KDE (both compositing/without compositing). Best regards, Ladislav By hard locks you mean you can't ssh in the computer ? There is a bug in my patches which lead to mutex/irqlock deadlock i don't understand it yet but i can happen and might explain your hardlock. Once i fixed those i will send new versions of the patches. I plan to latter add infrastructure to capture faulty instruction but this isn't yet done and this will likely need huge pile of code.
