Comment # 2 on bug 90523 from acab@digitalfuture.it

I am sorry, but while trying to get a crash I've realized it's not mesa.
The culprit appears to be llvm.

In short:
llvm 3.5.2 + mesa 10.5.5 -> ok
llvm 3.6.0 + mesa 10.5.5 -> lockup

I'm going to attach the logs anyway.
Feel free to close this bug if it doesn't belong in here.
