Title:
P620 reported TPM errors on Ubuntu 20.04
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
Thinkstation P620 will report TPM initial errors as follows on Ubuntu 20.04
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
root@lenovo-INVALID:~# dmesg | grep -i tpm
[ 2.052240] tpm tpm0: tpm_try_transmit: send(): error -5
[ 2.052257] tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling
instead
It seems to be TPM IRQ. The same P620 BIOS, such issue doesn't happen
on other OS.
Regards,
Jiqi.
