Cause
With firmware 8.21 and higher, a "
code:
chkdsk
" function is automatically executed at system initialization in order to perform a DOS file system corruption check, with repairs as possible. This function will occasionally find something that needs to be corrected.

Solution
If the first set of messaging ("
code:
...could not be repaired...
") is seen, then the repair routine could not fix all issues on this pass. If this occurs no more than a few times consecutively and is followed by the "
code:
...was repaired...
" messaging, then follow the "
code:
...was repaired...
" instructions below. Otherwise, if the condition persists in a reset loop then please contact the GTAC for assistance.

If the second set of messaging ("
code:
...was repaired...
") is seen, then the user should check that the configuration as displayed in the output of a '
code:
show support
' or '
code:
show config
' matches to the backup configuration file taken as of the last known config change. Apply any necessary corrections, but no action is warranted beyond that.
