Comment # 23 on bug 1187472 from Peter Aufner

Ok, it seems, I was too optimistic. I know that Bluetooth/Wi-Fi + Hibernate
worked once and that's it.
On second attempt Bluetooth was gone again, not even working after a regular
boot and hibernate works even less so. When I try to hibernate, I see the
following errors in dmesg:

[   99.409557] Bluetooth: hci0: SSR or FW download time out
[   99.409566] PM: dpm_run_callback(): acpi_subsys_freeze+0x0/0x20 returns -110
[   99.409584] hci_uart_qca serial0-0: PM: failed to freeze: error -110

It doesn't seem to matter, whether the firmware is packed or unpacked.

I've tried this both with the official repo kernel, as well as the HEAD kernel.
