With the latest kernel 5.0.8 the xhci_hcd and thunderbolt modules are crashing
leaving me without any peripheral devices.

- notebook Dell Inc. XPS 13 9370/0F6P3V, BIOS 1.8.1 02/14/2019
- Thunderbolt docking station CalDigit TS3 Plus

The bigger problem seems to be the error regarding xhci_hcd.
According to a suggestion from some forum I added pci=realloc to the
kernel command line. With this parameter xhci_hcd doesn't give any
error, the thunderbolt module is nevertheless crashing.
Mouse an keyboard are working now, but some other devices like the
smartcard reader attached to the Tunderbolt dock doesn't.
