Confirmed. On VT1, when unplugging my boot USB stick, I see various
lines about sdb3, sdb2 and sdb1 being removed, followed by "Bus
error". Nothing more happens, and the udev watchdog process is not
there anymore.

sajolida or others, can you please try to switch to VT1 before
removing the boot USB stick, and see if you get the same?

I suspect the "Bus error" message to be triggered by "pkill gdm3" in
udev-watchdog-wrapper.
