This was before `sudo ip link set lora1 up`...

Afterwards things seemed okay, but I didn't capture clk_summary again.

Possibly related, `sudo ip link set lora2 up` froze my system, with both
lora1 and lora2 being sx1301. (I should script bringing all of them up!)

Investigating...

And thanks go to the multiple vendors who donated SX130x hardware for
test coverage, helping catch non-standard bugs like these early!
