Intel Centrino Adv. N 6230 Wireless doesn't wake up again after suspend-to-RAM since Upgrade to 13.10

[Tobias Vogel]

Since I upgraded from Ubuntu 13.04 to Ubuntu 13.10, Wireless isn't working any more after suspend-to-RAM.
I'm using the amd64 version of Ubuntu on my Samsung NP900X3A-B03CH Ultrabook.
The Wireless-device is a (according to lspci)

Intel Corporation Centrino Advanced-N 6230 [Rainbow Peak]

This is what /var/log/syslog shows:

Nov 20 15:08:07 900X3A kernel: [ 32.372384] samsung_laptop: detected SABI interface: SwSmi@
Nov 20 15:08:07 900X3A kernel: [ 32.372390] samsung_laptop: Backlight controlled by ACPI video driver

Nov 20 15:08:09 900X3A NetworkManager[1851]: <info> Activation (wlan0) Stage 4 of 5 (IPv6 Configure Timeout) complete.

I'm rather surprised though, about this message rfkill2: found WiFi radio killswitch (at /sys/devices/platform/samsung/rfkill/rfkill2) (platform driver (unknown))
as the Computer doesn't have any hardware wifi-switch...?

[Tobias Vogel (tobias-vogel)]

Yes, absolutely - this happens always after a suspend-to-ram.
I don't really know how this bug could be fixed when you can't reproduce the bug on your side; what additional information can I provide?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Still occurs with 3.14-rc6.

I'm getting something similar with an 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)

If it sleeps, when this wakes I can't see any wifi networks at all even if I disable and re-enable wifi in gnome-shell.
