Hi,
I have an X1 Carbon laptop with an intel 7260 chip.
The automatic firmware loading doesn't work (kernel 3.17.2). I get this
in dmesg:
[ 1.615155] iwlwifi 0000:03:00.0: Direct firmware load for
iwlwifi-7260-10.ucode failed with error -2
The firmware then gets loaded by the userspace helper, however as far
as I understand it (and the description of the kernel option) this is
deprecated and shouldn't be used. Also, it takes quite a while
(minutes) till the wifi is available after boot which is quite annoying.
Any idea what I should do to debug/fix this? Is this a bug? (firmware
is the latest from intel's page, 23.10.10.0)
cu,

Most probably your rootfs is not yet mounted, when the driver attempts
to load the firmware file.
As a workaround try to compile iwlwifi as a module. When rootfs is
mounted, the module is loaded and the driver should pick up firmware.
