EFI Stub error - Unable to allocate memory for evernt logs

[gnanamsc]

Hello All,
We are facing this issue in all Linux machines with TPM error if we change the Hash policy from Sha-1 to Sha-2 we are observing the memory allocation error (attached the image for your ready reference). s. However it was not giving any problems apart from this error message. machine is working fine, but unsure of what may come up. Experts please guide me on this and help me to get the clarity.
Note: this is occurred in most of the client sites and further to that we are using Micropc from Advantech.

This can arise if you have the tpm chip, usually in laptops which you may be able to disable with:
systemctl disable tcsd.service.

Another approach is to disable kernel module tpm_infineon by adding: tpm_infineon.blacklist=yes, to the kernel command line.

It may not be be necessary to disable other tpm modules (tpm, tpm_bios, tpm_tis) though if they exist. Trial and error.

Fortunately, buggy BIOSes don't much bother linux after it takes over. None of this is likely to "give problems" to ordinary functioning as you mention.
