PROBLEM: TPM bug causes suspend to turn off device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello! I've reported the bug in bugzilla 
(https://bugzilla.kernel.org/show_bug.cgi?id=205409) but didn't see any 
activity so I thought I should cross-post here. Apologies if I should be 
posting somewhere else instead.

[1.] One line summary of the problem: TPM bug causes suspend to turn off device
[2.] Full description of the problem/report:

After finding this bug in Linux 5.1 I've bisected the kernel and have 
identified that the regression started with commit 
a3fbfae82b4cb3ff9928e29f34c64d0507cad874.

Reading journalctl before this commit would always show this on boot:

    tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16)
    tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling instead

Starting with the above commit, instead I saw:

    tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16)
    tpm tpm0: tpm_try_transmit: send(): error -5
    tpm tpm0: A TPM error (-5) occurred attempting to determine the timeouts
    tpm_tis 00:08: Could not get TPM timeouts and durations

I've tried removing the TPM module by adding blacklist commands 
/etc/modprobe.d/tpm.conf, but this doesn't seem to work. I can confirm that 
both `journalctl -b | grep -i tpm` and `cat /proc/modules | grep -i tpm` return 
no results when the module is disabled, but `systemctl suspend` still shuts 
down the computer.
