how about match this string "Machine Check Exception:" ? or can I use a pattern matching ?this is a memory failure at bank 12, usually indicates we need to replace this memory in bank 12,
here we internally have a tool depends on crash to analyze kernel crash and find out reasons and solutions, I hope the
"[Hardware Error]: CPU 14: Machine Check Exception: 5 Bank 12: fe00014b001000c3" line
can be matched, instead of the less useful
"Kernel panic - not syncing: Fatal machine check on current CPU" currently selected,
