Title:
Kernel freeze when plugging in external monitor via USB-C->DP-Adapter
Status in linux package in Ubuntu:
Confirmed
Bug description:
When plugging in/out my external monitor (Acer B286HK) via an USB-C ->
DP Adapter, there is a great chance, that the computer completely
freezes. SysReq-Keys are also not working.
I added a kernel.log where you can see the boot-up after one crash, than
plugging In/Out the monitor several times till a new complete freeze.
The graphics-card is the internal one of Core(TM) i7-7500Uin of the
XPS13 MLK (9360).
