The 11000 and 11050 platforms might intermittently fail to boot a newly installed hotfix. The symptom occur early in the booting process.


Installed hotfix fails to boot. The system posts error messages similar to the following: mount: could not find filesystem '/dev/root', setuproot: moving /dev failed: No such file or directory, setuproot: error mounting /proc: No such file or directory, setuproot: error mounting /sys: No such file or directory, switchroot: mount failed: Invalid argument, Kernel panic - not syncing: Attempted to kill init!

None. You must install a hotfix containing the fix.
