That's probably after I've put the computer in sleep mode (which works if I add tpm_tis to the module blacklist). Perhaps the same problem is related to this one: I just did a grep of my dmesg and saw some new error messages (28) in it. Perhaps they started occurring after I enabled it in BIOS. root@...to:/home/peter# dmesg | grep tpm_ [ 11.369198] tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16) [ 11.508115] tpm_tis 00:08: Adjusting TPM timeout parameters.
