3.1.0-rc7-00041-gb172e38 isn't any better:

[32755.040994] legacy_resume(): pnp_bus_resume+0x0/0x67 returns -19
[32755.040996] PM: Device 00:0a failed to resume: error -19

so which device is that? Second try succeeds.

Googling gives some hints about itpm option for tpm_tis... while trying to 
rmmod/modprobe it I got problem below. Anyway that shouldn't be itpm issue 
since:
[    7.088318] tpm_tis 00:0a: 1.2 TPM (device-id 0x1020, rev-id 6)
[    7.088320] tpm_tis 00:0a: Intel iTPM workaround enabled
so it is enabled already.
