A system fault can cause a card to go into the Panic state. After a card panics, it needs operator
or kernel intervention to start up. The kernel either reboots the card, or dumps and then reboots,
depending upon how variables are set in the Dump or Card profile.
An operator can use the grreset -h command to put a card into the Held_reset state to keep it
up but not transferring packets.
When the kernel cannot determine what a media card is doing, it places the card into State
unknown, and either reboots the card, or dumps and then reboots the card, depending upon
how variables are set in the Dump or Card profile.
