Title:
Kernel oops - unable to handle kernel NULL pointer dereference; IP:
intel_ddi_post_disable+0x54/0x170 [i915]
Status in linux package in Ubuntu:
Confirmed
Bug description:
I use Ubuntu 18.04.1 LTS on a Lenovo Thinkpad T460p.
Today I upgraded to Kernel 4.15.0-44 – since then my system crashes
when logging in (when the display resolution should switch). The
previous Kernel 4.15.0-43 works fine, though.
Here's the crash:
