[Bug 1472832] Re: Suspend issue with Dell Venue 11 Pro 7140

Tudor Holton:

1) As is known, folks with the same computer manufacturer and model can have different hardware under the hood, and/or different revisions of the same underlying hardware (i.e. one person can reproduce something another cannot). Hence, it wouldn't hurt to test the latest BIOS (A17) via https://www.dell.com/support/home/us/en/19/product-support/product/dell-venue-11-pro-7000-7140/drivers , given others have noted the issue resolved for them. Once done, could you please post the results of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

2) If still reproducible, could you please test the latest mainline
kernel (4.20-rc7) via https://wiki.ubuntu.com/Kernel/MainlineBuilds and
advise to the results? This will allow upstream developers to further
address.

Title:
Suspend issue with Dell Venue 11 Pro 7140

Status in linux package in Ubuntu:
Incomplete

Bug description:
Instead of suspending the machine into a state where it can be started
quickly, it appears that suspend causes the system to end up in a
state which requires a forced start. The power light is off, and the
only way to start the machine again is to hold down the power button
for more than 5 seconds. A quick check of uptime shows that it did,
indeed, start again.

I'm attaching a suspend log.
