[Dell Inc. Latitude E7240] suspend/resume failure

[Felix Lawrence]

This has happened twice today, the only change to my system was being connected to WPA2 enterprise wifi when suspending. Might be a coincidence.

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.

Same problem here with 14.04 and ralink rt73 chipset. Worked perfectly with 13.10

Not related with SUSPEND_MODULES="rt73usb" in /etc/pm/config.d/load (already done and doesn't resolve).

sudo rfkill list

kernel 3.14-1 from http://kernel.ubuntu.com/~kernel-ppa/mainline does'nt resolve the problem

[nicolas kleinklaus (nknico)]

Maybe it's not kernel related, cause actualy with 3.11 on 14.04, the wifi doesn't reconnect after suspend either...
