--- Comment #17 from Daniel daisuke14164@gmail.com --- Graphics: RV620/M82 Mobility Radeon HD 3450/3470 Kernel: 3.11.0-12-agd5f from mesa-git repo Mesa: ati-dri-git-57713.f2be639 from mesa-git repo OS: Arch ARCH: x86_64 Other: KDE 4.11 rc1
I installed mesa and linux packages from mesa-git repo, the linux-agd5f contains the lates patches. The system booted successfully 3 out of 4 times, and the temp of GPU is actually a little bit lower than before, about 3-4C(env temp 35C). But same as Sergey posted, the X respose is slow, about 1-2s delayed.
Here is my dmesg of drm and radeon.
