s3c2416 AW-GH321 (sdio8686 wifi)

[George Shore]

Hi Tommy,

One question I have: are you loading the libertas driver as a module, or is it being built-in to the kernel?
I had quite a similar problem where I had the driver built-in to the kernel with the firmware in /lib/firmware, and was receiving the same error. I found that the firmware loader is requesting the firmware through the sysfs interface, but at the time where the device is being initialised sysfs has not been mounted.
My solution was to compile the firmware blobs into the kernel image, which takes precedence over firmware on a filesystem.

Hope this helps,

George.
