I reported a bug on the bug tracker a bit ago but haven't seen any movement, so I figured I'd drop in here. My XPS 9560 has been having issues with its TPM, and all commands will fail with error 1 when operating on the TPM device. I managed to bisect it back to commit 4d6ebc4c4950595414722dfadd0b361f5a05d37e (tpm: fix invalid locking in NONBLOCKING mode) though it began failing with error 14 (bad address) at that point. I reported the bug at https://bugzilla.kernel.org/show_bug.cgi?id=206275 and attached some dmesg logs from boot there. Does anyone have any suggestions for additional debugging or such to figure out what's happening here? - Alex
