Sorry for jumping in. Finally, I found this thread.
My environment is completely different (ARM64 board), I am also suffering from a hibernation problem since this commit.
I get no response on the serial console after "Restarting tasks ... done." log message.
By reverting bf22ff45bed6 ("genirq: Avoid unnecessary low level irq function calls", I can get hibernation working again.
SW info: defconfig: arch/arm64/configs/defconfig DT : arch/arm64/boot/dts/socionext/uniphier-ld20-ref.dts PSCI : ARM Trusted Firmware
SoC info: CPU : Cortex-A72 * 2 + Cortex-A53 * 2 irqchip : GICv3 (drivers/irq/irq-gic-v3.c)
