[Samsung NP300E7A-A02DE] Reconnection after suspend to RAM doesn't work properly anymore

[Ettore Atalan]

Since the last distro upgrade to Kubuntu 14.10 (64 bit) from 14.04 (Kernel 3.13) the WiFi reconnection after suspend to RAM doesn't work properly anymore.

WORKAROUND: I switch back to suspend to RAM again and then doing a immediate wakeup.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 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.

Problem still exists in Kernel 3.18rc3.

[penalvch (penalvch)]

Ettore Atalan, could you please do the apport-collect while booted into the default Ubuntu kernel (not mainline/upstream)?

It is a Samsung NP300E7A-A02DE with latest BIOS update.

[penalvch (penalvch)]

Ettore Atalan, could you please test the latest mainline kernel 3.18-rc4 and advise to the results?

[Ettore Atalan (atalanttore)]

I have already tested the mainline kernel 3.18-rc3 with the same results.

Now I have installed the latest mainline kernel 3.18-rc4 with the same results. No change.

[penalvch (penalvch)]

Ettore Atalan, with the latest mainline kernel (3.18-rc5) could you please provide the missing information following https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[Ettore Atalan (atalanttore)]

Okay.
