That error is a command-specific error, and it means: Attempt to start
un-initialized watchdog

I'm guessing that the IPMI controller gets reset somehow and then thinks
it's watchdog timer is not initialized, and thus the reset command causes
an issue.

A fix should be pretty easy, if you get a 0x80 response from a reset,
re-initialize the timer.

Can you try the following patch?
