  • If your tablet rebooted unexpectedly, you need to save last_kmsg log. It will contain kernel log just before reboot and may show what caused reboot.
  • This allows saving the kernel printk messages to a buffer in RAM, so that after a kernel panic they can be viewed in the next kernel invocation, by accessing /proc/last_kmsg.

メモ

  • There are currently two competing debug facilities to store kernel messages in a persistent storage: a generic pstore and Google’s persistent_ram? by Colin Cross.
  • All the functionality is now supported by pstore and pstore_ram? drivers.
