6.8 Crashes

6.8.2 Crash recovery

Reboot the system. Examine the console output for information that may help determine the cause of the problem. If necessary boot in single user mode:

>b -s

or with an alternate kernel, e.g.:

>b sd()vmunix.gen

For best recovery after a crash have good backups and perform a file system check, fsck, when booting. If necessary reboot in single user mode and run fsck manually on an unmounted file system.
