This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

During kernel bootup, the tango platform blindly registers its pm ops in arch/arm/mach-tango/pm.c via initcalls() (without checking whether it's actually running on the correspondent hardware) and this causes OOPS during suspend on tegra platforms since the tango pm .enter function directly pokes the underlying hardware. Given the narrow scope of this SOC, i propose to disable support for the TANGO arch. Fix: Apply the attached patch and recompile. How to test: Suspend the tegra board and chek that it worked - either close the laptop lid, 'systemctl suspend' or: # echo -n mem > /sys/power/state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1787945/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
