Bug 479456 – LiveCD modules are loaded before the firmware is unpacked so the radeon module cannot find its firmware

• Status: RESOLVED FIXED
• Product: Gentoo Hosted Projects

[Description Tom Stellard 2013-08-02 03:37:46 UTC]

It looks like the firmware is not being unpacked to /lib/firmware on the LiveCD until after the modules have loaded.  This is a problem when the LiveCD is run on systems with radeon GPUs, since the radeon drm module requires the firmware at load time. 

Reproducible: Always

I've been playing around with this patch locally to great success.  There is not discernible point in tarballing the firmware anyway:

I've tested this patch and it fixes the bug for me.
