Messages following a crash: [Hardware Error]: event severity: fatal

I just had the system lock-up hard, requiring hitting the reset button. I now see in the system log: Jan 11 19:28:54 e7 kernel: BERT: Error records from previous boot: Jan 11 19:28:54 e7 kernel: [Hardware Error]: event severity: fatal Jan 11 19:28:54 e7 kernel: [Hardware Error]: Error 0, type: fatal Jan 11 19:28:54 e7 kernel: [Hardware Error]: section_type: Firmware Error Record Reference Jan 11 19:28:54 e7 kernel: [Hardware Error]: Firmware Error Record Type: SOC Firmware Error Record Type1 (Legacy CrashLog Support) Jan 11 19:28:54 e7 kernel: [Hardware Error]: Revision: 0 Jan 11 19:28:54 e7 kernel: [Hardware Error]: Record Identifier: 100300100000000 Jan 11 19:28:54 e7 kernel: [Hardware Error]: 00000000: 00000000 00000000 00000000 00000000 ................ ... continue until Jan 11 19:28:54 e7 kernel: [Hardware Error]: 00000c00: ffffffff ffffffff ffffffff ffffffff ................ I understand that this is related to the preceding crash. If so, what does it tell me? Doing a search suggests that if this happens rarely then it can be ignored- true?.\ I now see that I had it also last Oct but not earlier. This hard lock-up happens at times (more than twice for sure) and if I can do something about it then I would. TIA -- Eyal Lebedinsky (fedora(a)eyal.emu.id.au)
