A warning to anybody considering to use the suggested work-around.
Based on the information suggested in this bug, I put the following in
`/etc/modprobe.d/local.conf` on my laptop:
options iwlwifi enable_ini=0
in order to suppress the "failed to load iwl-debug-yoyo.bin (-2)" log
message.
Versions 66 and above of the iwlwifi-ty-a0-gf-a0 firmware would refuse to
load with these error messages:

Versions 63 and below of the firmware would load just fine with
"enable_ini=0" which suggests to me that this version of the firmware would
simply ignore it.
Much worse, versions 74 or newer of the firmware would lock up and require a
full power off (unplugged from power) to successfully load a firmware again
(even 63 or below).
Hopefully this comment will save someone some troubleshooting time. My
solution is simple: ignore the "failed to load iwl-debug-yoyo.bin (-2)" for
now.
