I recently flashed my Lenovo ThinkPad X220 with Coreboot and a SeaBIOS payload. I made an attempt to document the whole process[0].
Initially, everything seemed to work fine. I was able to boot to SeaBIOS which handed off to a Debian testing install (Stretch). Now that I've used this laptop a bit, I realized that wifi appears hardware-blocked after returning from suspend. I've found lots of pages online with "one weird trick" to fix this, and have tried many of those tricks to no avail :( I've tried a couple of different Coreboot configs[1][2] neither of which made any difference. After re-flashing the old proprietary ThinkPad BIOS wifi comes back from suspend just fine. I've tried both the standard intel wifi card and a card from ThinkPenguin that uses the ath9k driver[3] using the coreboot config. Any help or pointers anyone could give me would be much appreciated! -- Tyler [0]. <https://tylercipriani.com/blog/2016/11/13/coreboot-on-the-thinkpad-x220-with-a-raspberry-pi/> [1]. <http://pastebin.com/Ah0fxBp5> [2]. <http://pastebin.com/1yNSTfyj> [3]. <https://www.thinkpenguin.com/gnu-linux/penguin-wireless-n-half-height-mini-pcie-card>
