Ubuntu freezes when suspending (to RAM)

[Francisco Cribari]

I installed Ubuntu 15.04 on a DELL XPS 13 notebook (2015 edition, model 9343, bios A03, dual boot w/ Windows). I am having an annoying problem. Oftentimes Ubuntu crashes/freezes when I try to suspend (to RAM). I have already reinstalled Ubuntu (fresh reinstall) but the problem persists. I ran the bios diagnostic check (even the extended one) and no hardware problems were detected. I also ran a memory check via Windows and again no memory problems were detected.

The problem: Sometimes when I try to suspend the computer freezes: the screen turns blank and the CAPS LOCK key indicator blinks. I am unable to ssh into the machine. The problem also happened with previous kernels.

After installing Ubuntu, I did the following (for my bluetooth to work):

wget https://www.dropbox.com/s/r2pb41rhx65t9zi/BCM20702A0-0a5c-216f.hcd
sudo cp BCM20702A0-0a5c-216f.hcd /lib/firmware/brcm/
sudo modprobe -r btusb
sudo modprobe btusb

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Francisco Cribari, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.
