Hi, trying and testing...
I can get even more scarier errors from i915. I tried various combination of enabling wifi before/after As you can see, the buffer underrun appears after some moments, after I completed login. So we have 1) CPU Pipe A FIFO underrun 2) CPU Pipe B FIFO underrun 3) failed to load DMA map for stolen object: -22 4) failed to load DMA map for stolen object: -22 again 5) after a while CPU Pipe A FIFO underrun again are there other old i915 owners?
