Thanks. I think the other problem is that
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifihttps://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
says to use 'iwlwifi-8000-ucode-16.242414.0.tgz' for 4.3+ kenrels.
and strangely says "iwlwifi-8000-ucode-25.30.13.0.tgz" for 4.1+ kernels.

Unless I'm crazy, it didn't have -25 when I looked last time.
Is there a way to keep what I thought was the canonical page, up to date?

Firmware 27 seems to work, but I'm getting allocation error/warnings?
