[PATCH] take Hardware Error & kernel pointer bug as separate panicmsg
by drc＠yahoo-inc.com
There are just too many kinds of panic types are categorized under
the same Oops: xxxx, makes this field really ambiguous and not so useful
PANIC: "Oops: 0000 [#1] SMP " (check log for details)
this patch separated 3 kinds of panicmsg out, as the most happening cases
among the machines managed by me; the match string are copied
from kernel source code exactly, after applied, I got panicmsg like:
include/linux/kernel.h:#define HW_ERR
panicmsg: "[Hardware Error]: CPU 7: Machine Check Exception: 5 Bank 11: f200003f000100b2"
drivers/char/sysrq.c:__handle_sysrq
panicmsg: "SysRq : Trigger a crash"
arch/x86/kernel/traps.c:do_general_protection
panicmsg: "general protection fault: 8800 [#1] SMP"
arch/x86/mm/fault.c:show_fault_oops
panicmsg: "BUG: unable to handle kernel paging request at 00001248a68eb328"
