The retry count was initially set to 10, which with the 5 second
timeouts give 55 seconds to fail a message.
The IPMI spec specifies the 5 second timeout, and it specifies retries
for KCS but does not specify a number. 55 seconds is a long time, so
reduce retries to 2. It matches the default in the BT state machine.
This is 15 seconds, then, which is still a long time, but more
reasonable.
