7i92T+7i85s+7i76+SSI = Waiting for component 'hm2_eth' to become ready...

Hello.
I've been trying to make a pair of absolute encoders work with my setup. Tried to change the firmware to swap the unused sserial interfaces on both 7i76 and 7i85s with ssi, which seems successful:
With new firmware and old config (config="num_encoders=5 num_pwmgens=0 num_stepgens=9 sserial_port_0=0xx") machine loads and works as usual.
But when I change this line to
config="num_encoders=5 num_pwmgens=0 num_stepgens=9 sserial_port_0=0xx ssi_chan_1=error%3bposition%24g"
The linuxcnc doesn't load, it infinitely freezes at "Waiting for component 'hm2_eth' to become ready..."
Not really sure where to dig, and would appreciate any help.
Attached is a vhd file for firmware I made

See the link, there should be a working config attached there

Thanks, haven't found this thread before.
Changing 'position%24g' to 'position%24ge' made a difference, now linuxcnc does load
