#81719 — Bug#966218: Warning about the work-around listed here

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.

Thanks for the warning and your solution seems sound to me.
