Kernel panic (unrecoverable/tainted) for unix/linux

Or streamed large files (movies), hit disk full (bet there's a rather small and thus inexpensive SD card present), aborted bringing down X and forcing system reboot where upon next boot fsck hit duplicated blocks

Technically it didn't crash per see, it rebooted due to disk failure and stopped because automatic recovery might make things worse (crosslinked i-nodes - two files occupying the same space).
