Bug description:
  I'm using Lubuntu 20.04 on Dell XPS 13 9360. Somehow thunderbolt
  stopped working. I've attached the relevant output from /var/syslog.
  I'm using 5.4.0-52-generic. I've updated all my firmware through
  fwupdmgr.

  Briefly, the kernel complains 
  kernel: pci 0000:01:00.0: BAR 13: no space for [io  size 0x3000]
  kernel: pci 0000:01:00.0: BAR 13: failed to assign [io  size 0x3000]

  then
  kernel: usb 3-1.3: config 1 has no interfaces?

  then

  kernel: xhci_hcd 0000:39:00.0: xHCI host controller not responding, assume 
dead                                                                        
  kernel: r8152 4-1.4:1.0 enxd481d70b2831: Stop submitting intr, status -108
  kernel: xhci_hcd 0000:39:00.0: HC died; cleaning up

  then 
  kernel: xhci_hcd 0000:39:00.0: Host halt failed, -19
  kernel: xhci_hcd 0000:39:00.0: Host not accessible, reset failed.             

  then

  kernel: pcieport 0000:00:1c.0: AER: PCIe Bus Error: severity=Corrected, 
type=Physical Layer, (Receiver ID)
