Occasionally I see this, too. Today I waited a bit longer and got more
output after some time:

	udevd[422]: timeout: killing '/sbin/modprobe -b acpi:SMO1200:PNP0C31:' [444] (repeated many times)

	udevadm settle - timeout of 120 seconds reached, the event queue contains:
	... blurred image ...
	LNXSYSTM:00/device:00/PNP0A08:00/device:0a/SMO1200:00 (852)
	udevd[422]: timeout: killing '/sbin/modprobe -b acpi:SMO1200:PNP0C31:' [444]

(copied from a photo) than the booting process continued as usual.

SMO1200 is my laptop's TPM chip.

Best regards
Uwe
