Dear Linux folks,
On a Dell PowerEdge R7525 with AMD EPYC 7763 64-Core Processor, Linux 5.15.94 logs the machine check exceptions (MCE) below:
``` [5154053.127240] mce: [Hardware Error]: Machine check events logged [5154053.133711] mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 17: d42040000000011b [5154053.141948] mce: [Hardware Error]: TSC 0 ADDR b3cbdbbc0 PPIN 2b615bef7f48098 SYND 6bd210000a801002 IPID 9600650f00 [5154053.152893] mce: [Hardware Error]: PROCESSOR 2:a00f11 TIME 1679213602 SOCKET 0 APIC 6 microcode a001173 [5608214.292978] mce: [Hardware Error]: Machine check events logged [5608214.299771] mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 17: d42040000000011b [5608214.308066] mce: [Hardware Error]: TSC 0 ADDR b3cbdbbc0 PPIN 2b615bef7f48098 SYND 6bd210000a801002 IPID 9600650f00 [5608214.319102] mce: [Hardware Error]: PROCESSOR 2:a00f11 TIME 1679667766 SOCKET 0 APIC 6 microcode a001173 [5707500.646385] mce: [Hardware Error]: Machine check events logged [5707500.652973] mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 17: d42041000000011b [5707500.661238] mce: [Hardware Error]: TSC 0 ADDR b3cbdbbc0 PPIN 2b615bef7f48098 SYND 6bd210000a801002 IPID 9600650f00 [5707500.672271] mce: [Hardware Error]: PROCESSOR 2:a00f11 TIME 1679767053 SOCKET 0 APIC 6 microcode a001173 [5810063.788078] mce: [Hardware Error]: Machine check events logged [5810063.794698] mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 17: d42041000000011b [5810063.803126] mce: [Hardware Error]: TSC 0 ADDR b3cbdbbc0 PPIN 2b615bef7f48098 SYND 6bd210000a801002 IPID 9600650f00 [5810063.814264] mce: [Hardware Error]: PROCESSOR 2:a00f11 TIME 1679869617 SOCKET 0 APIC 6 microcode a001173 ```
Does GNU/Linux offer a way to decode this automatically?
Kind regards,
Paul
