>Description:
After using /stand/sysinstall to create a file system and partitions, the system practically ceases to exist. Commands are reported as not found, cd reports not found as well. New processes can not start, system becomes unusable and unstable. Soft reboot procedure is unable to complete properly (panics), data loss may occur. This can be a very serious problem when an admin attempts to do some disk configuration on a live system.
>How-To-Repeat:
System is an Intel D815EEA2 Desktop Board, 850Mhz Celeron CPU, 256MB RAM. Tested with an IBM and Seagate 20 gig hd. ad0 == root hd, ad2 == blank, unmounted hd.
