For the failure mode that a disk is not recognized if plugged in _after_ resume, please provide kernel logs with firewire-ohci IRQ logging enabled:

# echo 7 > /sys/module/firewire_ohci/parameters/debug
(suspend)
(resume)
(attach FireWire disk)
(collect the dmesg)

To be sure, repeat this with additional logging of bus reset events:

# modprobe -r firewire-ohci
# modprobe firewire-ohci debug=15
(suspend)
(resume)
(attach FireWire disk)
(collect the dmesg)

Beware, either debug level may possibly cause huge logs.
