As I noticed microcode was no longer being loaded on v4.6-rcX I switched to builtin microcode as described in
Documentation/x86/early-microcode.txt
So I have now this: CONFIG_FW_LOADER=y CONFIG_FIRMWARE_IN_KERNEL=y CONFIG_EXTRA_FIRMWARE="intel-ucode/06-2a-07 radeon/REDWOOD_me.bin radeon/REDWOOD_pfp.bin radeon/REDWOOD_rlc.bin radeon/REDWOOD_smc.bin radeon/CYPRESS_uvd.bin" CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" # 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.
