Hi , 5.16 series is EOL so I've just continued to do tests with vanilla linux-5.17.4 and linux-5.17.5 : both do not boot and stop at the same point as indicated in the messages above _but_ ... something strange is happening also with longterm 5.15 series since version 5.15.35 and 5.15.36 do not boot too.
The kernels are both custom but the config for both versions is exactly the same. The following lines are the last ones appearing over the screen : [ 3.736342] ima: No TPM chip found, activating TPM-bypass! [ 3.736360] ima: Allocated hash algorithm: sha512 [ 3.736401] ima: No architecture policies found [ 3.736429] evm: Initialising EVM extended attributes: [ 3.736431] evm: security.selinux [ 3.736433] evm: security.SMACK64 (disabled) [ 3.736435] evm: security.SMACK64EXEC (disabled) [ 3.736437] evm: security.SMACK64TRANSMUTE (disabled) [ 3.736438] evm: security.SMACK64MMAP (disabled) [ 3.736440] evm: security.apparmor [ 3.736442] evm: security.ima [ 3.736443] evm: security.capability [ 3.736445] evm: HMAC attrs: 0x1 <------ They stop booting here Not the same point as in 5.16 and 5.17 cases , but with the same result. So at the moment , at least in my case , the last working kernel is version 5.15.34
