Wow! ,from LKML , I have found your patches here : http://www.spinics.net/lists/linux-acpi/msg34003.html I check the latest code from http://lxr.linux.no/linux+v3.2.1/drivers/acpi/apei/ghes.c ,this patch has been not adopted by upstream. another question : for corrected error , hardware can correct it. but for uncorrected error, especially fatal error , machines need to be restarted immediately, but for OS ,for different error (NMI sourcing) ,OS needs to do different ready works before restarting machine ? thanks . -Bob Zhang -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
