Raising Skinny Elephants is Utterly Boring (or: if all else fails)

The magic key codes on Linux systems:

press Alt + SysRQ ("print") +

  • R keyboard → raw mode
  • S sync disc
  • E terminate all processes
  • I kill all processes
  • U remout all filesystems read-only
  • reboot

That works almost all the time. Even after problematic errors.
