I cannot say = how much this file would be in its binary version but I would think it would on= ly be like 10% of it, so like 45kb since the parsed contents also display whole certificate chains. I don't see why 45kb should be an issue. Can you attach the plain binary file? > When the TPM2 ACPI table sets the Minimum Log Length size more then 4MB, a > call trace occurs during the boot time. The reason is the kmalloc limits = the > maximum size to 4MB for x86 arch. 4MB would be excessive and I think would hint at a buggy BIOS. We should ne= ver allocate that much memory for the BIOS log. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
