The error message I get is slightly different: " tpm_crb: probe of MSFT0101:00 failed with error 378 "
As https://bugs.launchpad.net/bugs/2047692 was marked as duplicate of this ticket I'll add my original comment here, too - sorry if this breaks launchpad's rules. 6.2.0-39.40~22.04.1 includes upstream stable patchset 2023-10-10 (https://launchpad.net/bugs/2038969) with the TPM changes 'Disable RNG for all AMD fTPMs' and 'Add a helper for checking hwrng enabled'. This causes on some Intel devices that TPM does not work (in my case a Gigabyte Brix GB-BSi5-1135G7). Upstream discussed this issue in https://bugzilla.kernel.org/show_bug.cgi?id=217804 and a fix was found: https://github.com/torvalds/linux/commit/8f7f35e5aa6f2182eabcfa3abef4d898a48e9aa8 (already linked by ~badsmoke in an earlier comment) ** Bug watch added: Linux Kernel Bug Tracker #217804 https://bugzilla.kernel.org/show_bug.cgi?id=217804 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2046434 Title: TPM2 Problem in 6.2.0 kernel Status in linux package in Ubuntu: Confirmed Bug description: after updating to kernel 6.2.0-39 i`ve got a problem with TPM on variuos notebooks or desktops.
