Same here.
And I bisected the issue to commit 7279b238ba, "mei: send OS type to the
FW"

Suspending from the console with no_console_suspend shows that the last
message is "e1000e: EEE TX LPI TIMER: 00000000" (which is probably
unrelated).

More interesting is the first message missing, ie. the one after the one
mentioned when using a working kernel: "ACPI : EC: event blocked".

This seems to be related to the bisected commit. Maybe it's not even the
kernel's fault, but the EC just happens to change it's behavior when it
got told about the OS type, before?
