Title: TPM_CRB probe fails on ASUS N552V, causes system to freeze while starting Status in systemd package in Ubuntu: Won't Fix Bug description: While starting up (arranged by systemd, the problem is in the kernel), The system attempts to perform some kind of probe, when that happens, there is 50% chance that the system simply freezes. It always occurs when these lines pass the screen (and are found on dmesg on a running instance): [ 8.351515] tpm_crb MSFT0101:00: can't request region for resource [mem 0xfed40080-0xfed40fff] [ 8.351550] tpm_crb: probe of MSFT0101:00 failed with error -16 I have noticed that this particular problem occurred in earlier releases of the kernel. I have the same problem in any of the following kernels: 4.8.0-36-generic 4.8.0-39-generic 4.8.0-41-generic It is annoying, as I have to restart the system manually with a change of failure. Sometimes it takes over five reboots to get passed this problem. Which indicates that somehow the problem doesn't always lock the kernel from booting. I hope you'll find an answer to this problem.
