I'm running archlinux on a Dell XPS15 9550 and I connect it to a TB16
thunderbolt dock. Connected to the dock I have a 4k external display and
a USB logitech transmitter for my wireless keyboard and mouse.
The module 'xhci_pci' is automatically unloaded/reloaded on
suspend/resume to make the TB16 dock work properly across suspend/resume
cycles.
Yesterday, I updated my kernel from 4.14.16 to 4.15.1 and now I get a
kernel oops on suspend. I can replicate the oops every time: boot
computer, connect to thunderbolt dock, suspend.
I managed to get some logs of the kernel oops from EFI pstore. Find
attached with this email.
