Hi Tony, With commit 0bb77c46 "pstore: X86 platform interface using ACPI/APEI/ERST" when reboot the server kernel will call erst_writer() to write CPER_NOTIFY_MCE to ERST, if reboot the server to Windows we find MCE from system event logs. Any reason write this to ERST when reboot? Any input will appreciate!
