Hibernation problem with 3.14 kernel

Hi everyone,

I hope I am posting in the right section.
Since the upgrade to kernel 3.14 I am unable to hibernate. I am using Archlinux.
I am hibernating with "systemctl hibernate".
It always fails to freeze device 00:08:

journalctl tells me:
kernel: serial 00:08: disable failed
kernel: dpm_run_callback(): pnp_bus_freeze+0x0/0x20 returns -5
kernel: PM: Device 00:08 failed to freeze: error -5

lspci -v tells me:

0:08.0 PCI bridge: NVIDIA Corporation MCP78S [GeForce 8200] PCI Bridge (rev a1) (prog-if 01 [Subtractive decode])
Flags: bus master, 66MHz, fast devsel, latency 0
Bus: primary=00, secondary=01, subordinate=01, sec-latency=64
Capabilities: [b8] Subsystem: ASUSTeK Computer Inc. Device 82e7
Capabilities: [8c] HyperTransport: MSI Mapping Enable+ Fixed-

My mainboard is a ASUS M4N98TD EVO.

What does error code -5 mean? How do I debug this further? Should I file a bug?

Cheers,

Faerbit

Hi,

It's not that device, what fails is a serial drvier.

This is an error code returned by the driver, I'm not sure what it means for pnp_bus_freeze() from the top of my head (will check later).

If that's 100% reproducible, you can try to bisect.

Yes, please. At bugzilla.kernel.org, against power management (hibernation/suspend).

Thanks!

I speak only for myself.
