I mean finding the "fix", i.e. when it started to work again.
Ok, I reverted back to 7.10.2 and libdrm 2.4.23. but the bug didn't show up as I expected. But by also reverting the kernel back to 2.6.32 the bug was there again.
So Mesa 7.10.2 + Kernel 2.6.32 -> bug Mesa 7.10.2 + Kernel 2.6.38 -> no bug
It seems that it actually was a kernel issue and not a Mesa one.
