And? Why does the user care? I mean, it is good for debugging when you wanna see you're parsing the error info data properly but otherwise it doesn't improve the error reporting one bit. > Because these are part of the error information structure.

(UEFI spec 2.6 table 261) So that's IP-dependent and explained in the following tables. Any plans on decoding that too? > Why's that?

Even in your example you have: [ 140.739210] {1}[Hardware Error]: 00000000: 4d415201 4d492031 453a4d45 435f4343 .RAM1 IMEM:ECC_C [ 140.739214] {1}[Hardware Error]: 00000010: 53515f45 44525f42 00000000 00000000 E_QSB_RD........ Which looks like some correctable ECC DRAM error and is actually begging to be decoded in a human-readable form. So let's do that completely and not dump partially decoded information. -- Regards/Gruss, Boris.
