As I noticed microcode was no longer being loaded on v4.6-rcX I switched
to builtin microcode as described in
So I have now this:
radeon/REDWOOD_pfp.bin radeon/REDWOOD_rlc.bin radeon/REDWOOD_smc.bin
# CONFIG_FW_LOADER_USER_HELPER_FALLBACK is not set
That works, i.e. when booting as very first line I get message microcode
is loaded, see attached dmesg
However, after suspend to ram, trying to resume results in total lockup
of the machine: no ping, no sysrq-keys, only hard reset works.
Trying to bisect this didn't really work, earlier kernel (v4.5) doesn't
even boot with this config.
I'm seeing this on 2 rather different machines, on intel quadcore on 2-3
year old mobo and a dual core pentium on fairly new mobo.
Note that both machines do boot using EFI.

Yes, it boots / suspends / resumes just fine.
(but no microcode updates in dmesg)
