           Summary: intel driver crashes with kernel 5.1.2 when booting
                    with external monitor connected to Mini-Displayport
           Product: DRI
           Version: unspecified

journalctl -k -b -1 output

I have a Lenovo Carbon X1 Notebook with an external monitor connected to my a
Mini Display Port.

After updating from 5.0.13.arch1-1 to 5.1.2.arch1-1, the intel driver appears
to crash after starting X (at least the mouse and keyboard get unresponsive)
when I boot with the external monitor connected. However, booting without the
external monitor works just fine, and I can plug it in afterwards without
experiencing any problems. Unfortunately I cannot get a dmesg, but journalctl
logs are provided below.

Reverting to an earlier kernel version solves the problem.

The culprit seems to be:

Please find attached the complete logs run with drm.debug=0x1e log_buf_len=1M. 

Right now I'm not able to bisect, however I'll try my best to provide more
information if needed.
