It's not published yet but the build of kernel-default already finished, so you can fetch binaries via "osc getbinaries home:tiwai:bnc1088658/kernel-default" There is a known regression wrt swiotlb, and this looks like that. -- You are receiving this mail because: You are on the CC list for the bug.

I don't see the call trace anymore. I had a few flickers when starting firefox, but there stopped. I think that the kernel fixes the issue!

I refreshed the repo home:tiwai:bnc1088658 with a couple of more patches to improve the memory allocations. I'm not sure whether the symptom is relevant with it, but in anyway, please give it a try later (now it's being built, so one hour later or so). -- You are receiving this mail because: You are on the CC list for the bug.

I still have some flickering I dunno where it is coming from or what is causing it.
