And, "console=ttyS0" on it's own is particularly bad because it seems to default to a baud rate of 9600 (at least, setting it to 115200 on my NUC improved things considerably, but the boot is still slower than without the serial console option). Add that to the fact that the kernel is quite noisy o

I think the reason for your issue is that the final 2 events extended to PCR7 are recorded twice in the log, most likely because the test kernel from comment 12 doesn't contain https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=166a2809d65b282272c474835ec22c882a39ca1b I

Hi, In response to your queries: 1) With kernel version 5.0.0-37, I can confirm that the event log provided by the kernel is inconsistent with the TPM for PCR7 in a VM that's running OVMF. This is because of the opposite problem - in this case, the last event is missing from the log exported by t

Ok, I think that the truncated log issue with kernel version 5.0.0-37 is a bug in tpm1_bios_measurements_next() which is fixed by https://lore.kernel.org/patchwork/patch/1031236/, although I've not verified that this is the case. -- You received this bug notification because you are a member of K
