I'm running Ubuntu 15.10 server on a Asrock E3C226D2I board. When I get a kernel update or run update-initramfs -u I get a warning about missing firmware:
root@fileserver:~# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.2.0-27-generic
W: Possible missing firmware /lib/firmware/ast_dp501_fw.bin for module ast
I can't find much information on this particular firmware, other than it is probably for my video card. Since I'm running a server I don't really care about graphics (no monitor attached).
All works fine so I'm ignoring it for now but is there a way to fix this?
