Hi Jerry, It looks like there still is an issue with the recent changes to the tpm_tis IRQ handling. At least I think those are the cause I did not dive any deeper, I just noticed that we (Fedora) have been receiving an aweful lot of kernel tpm_tis_send_data backtraces with most starting with tpm_tis_probe_irq_... See for example: https://bugzilla.redhat.com/show_bug.cgi?id=1912167 https://bugzilla.redhat.com/show_bug.cgi?id=1927610 Those are just the 3 which landed in my inbox today, for much more see: https://bugzilla.redhat.com/buglist.cgi?quicksearch=tpm_tis_send_data (this shows 18 bugs atm). These were reported through the Fedora ABRT tools which automatically collects backtraces, the bugs have links to the ABRT reports, e.g. : https://retrace.fedoraproject.org/faf/reports/28155/ https://retrace.fedoraproject.org/faf/reports/37107/ The 28155 report says that so far there have been 308,412 (ouch) automatic uploads of that particular variant of these backtraces Note the second (37107) retrace report is about this happening on resume, rather then on probe/tpm_tis_probe_irq_... time. Did your work on this work land in 5.10 ? Or could it be that the issue is an incomplete backport to the 5.10.y stable series ? Regards, Hans
