Feedback on the Dell Latitude 5401 - Freezes after suspend / resume

Asked by Ailin Nemui

Got a fresh new Dell Latitude 5401 with Intel i5 9th gen CPU.

I was using the Vendor-installed Ubuntu 18.04 with Dell OEM Kernel.

After suspend and resume, the system is still responsive for a few seconds before entering a hard freeze. The fan starts spinning and I have to hold power button for 10s and force off the system.

This is reproducible for me 100%.

Upgrading the Kernel for example to 5.4 as provided in the linux-generic-hwe-18.04 does work around the issue, but it's rather sad that such a "Certified" system is shipped with a broken default install.

Hi Ailin. So far I could only try reproducing this on a Latitude 5401 with an i7 CPU. This model didn't freeze with either kernel version 4.15.0-1037-oem or 4.15.0-1100-oem. Do you remember the exact kernel version you used before upgrading, or can you check your logs?
