You should also backport this patch(*): 96b010536ee0 efi/cper: align ARM CPER type with UEFI 2.9A/2.10 specs It fixes a bug at the UEFI parser for the ARM Processor Error record: basically, the specs were not clear about how the error type should be reported. The Kernel implementation were assuming that this was an enum, but UEFI errata 2.9A make it clear that the value is a bitmap. So, basically, all kernels up to 6.18 are not parsing the field the expected way: only "Cache error" was properly reported. The other 3 types were wrong. (*) You could need to backport those patches as well: a976d790f494 efi/cper: Add a new helper function to print bitmasks 8ad2c72e21ef efi/cper: Adjust infopfx size to accept an extra space Regards, Mauro Thanks, Mauro
