To head that off at the pass, this generally occurs while linuxcnc isn't
running, and here is the hal code that starts it on the 6040:
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD
num_joints=[KINS]JOINTS num_dio=12
loadrt hostmot2
loadrt hm2_pci config="num_pwmgens=1 num_stepgens=4 num_encoders=1
sserial_port_0=1xxx"
Here is the failing startup:
gene@shop:~/linuxcnc/configs/6040-5i25-7i76$ linuxcnc -l

Note total lack of response from the sserial. The 7i76 simply isn't
there. A power cycle long enough to extinguish the leds will reset it
and it will work again till the next time. Might work for a week,
might work for a couple months. That computer is an ARK shoebox with
an intel D525-MW motherboard in it.
As I said I would check the 5I25 power jumpering (and 5V ,field power when it
fails), I have multi-year uptimes of 7I76 Firmware running on test systems, I
really think something else is going on
Its current uptime:
00:34:40 up 40 days, 12:04, 5 users, load average: 0.00, 0.01, 0.05
Anything I missed, I can get tomorrow night or Thursday when I get
back from the heart mechanics, its not fussy and its not going away
till I do a powerdown reset, or somebody points out the init error in
the hal code above.
I'm just up rubbing theraworks into my cramping legs and to munch
on a couple antacids which will usually abate the leg cramps that
plague the elderly at night.

I did a quick test to see if I could confuse a 7I76 by sending it
garbage/interrupted transmissions (cycling the FPGA side power while
doing high speed comms. I did this 500 times without the 7i76 I/O
processor ever requiring a power cycle to recover. I still think this
is some other issue (power?)
