The kernel seems try to set up the interrupt and send data, but failed.
After got error returned, the kernel will disable interrupt and using polling instead.

I beleve it will have the following messages in dmesg log
kernel: tpm tpm0: tpm_try_transmit: send(): error -62
kernel: tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling instead

The call trace seems from the patch which add the checking for the invalid status,
