All,

We are seeing a problem with one MAXv motor controller in a crate with 6
controllers running the version 6.4.3 of the motor support with Base
3.14.10 on RTEMS 4.9.3.  The symptoms I see are that the IOC becomes
unresponsive.  After a soft reboot of the CPU I see the following on the
console

MAXv card #3 is NOT running; status = 0x2

This message is printing the firmware state register, which is
indicating that the processor on the maxv card is still
(re)initializing.

The IOC then hangs waiting for a reply from the card in motor_init.  I
can attach with a remote debugger and see that it is stuck in a loop
waiting for the card to update a register.  A full power cycle seems to
bring the card back to life, but the problem has recurred several times
in recent weeks.

Is this a known issue with a fix?  We do have a spare, so I am inclined
just to return this one to the manufacturer.
