Are you thinking that there's some interoperability issues between kernel |
| 11 |
versions and firmwares? My impression is that's generally not a problem, so |
| 12 |
wouldn't be too worried about trying different kernel versions. |
| 13 |
|
| 14 |
So the steps are just; |
| 15 |
- identify the correct firmware |
| 16 |
- verify its in /lib/firmware (typically just emerge linux-firmware, but |
| 17 |
sometimes others from /usr/portage/sys-firmware/ ) |
| 18 |
- configure the kernel to load it (in this case follow Floyd's instructions) |
| 19 |
- build and install new kernel |
| 20 |
- reboot |
