Tried 5.8.0-43 kernel and didn't work.
I also tried booting Manjaro which uses 5.6.15-1-MANJARO and the issue is
present.
I ended up doing a workaround, compiling an ubuntu kernel with `pci-
stub` as builtin and `xhci-hcd` as a dynamic module. That way I can make
pci-stub bind to the culprit

Hey !
I'm able to boot and get into a tty. But after a few seconds (even if I
don't do anything) it freezes.
Machine boots fine with the USB stick and running lspci doesn't trigger
a freeze.
Attached is the dmesg log, but it seems to be truncated. I managed to
log into a tty and run `dmesg -w`
You can see the image contains a few more logs that couldn't be written
to the disk

Public bug reported:
After upgrading from Ubuntu 18.04 to 20.04 my computer started to freeze
when running lspci.
I ended up noticing that it happened when trying to query device
'1f:00.0' a USB port. After some kernel and bios updates the problem got
worse. Now the computer freezes ~5 seconds
