My apologies in advance if this is not the appropriate forum / list to post this. If so, please forward me to the appropriate one(s). My kernel was upgraded to 4.10.5-200.fc25.x86_64 this morning. Since then, I have received the following system error messages, all related to supposed hardware errors: Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: CPU 2: Machine Check: 0 Bank 128: 000000008802000b Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: TSC 7f538132a1 Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1490710022 SOCKET 0 APIC 2 microcode 1c Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 128: 000000008802000b Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: TSC 7f538162d6 Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1490710022 SOCKET 0 APIC 3 microcode 1c Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 128: 000000008804000a Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: TSC 7f53acb914 Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1490710022 SOCKET 0 APIC 3 microcode 1c Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: CPU 2: Machine Check: 0 Bank 128: 000000008804000a Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: TSC 7f53acc428 Message from syslogd@Bre at Mar 28 11:07:02 ... kernel:mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1490710022 SOCKET 0 APIC 2 microcode 1c Any hint on what may be happening? Anyone else seeing this? I have the copr repo active and enabled for package download. Thanks in advance!
