5.3.0-050300rc4-generic was slower to suspend but the same happens. The laptop is suspended less than a second and just enough to see the fading powerlight indicating sleep mode before it resumes.

It immediately wakes up after going through all the usual steps of turning off the screens, USB devices etc. I'm using the UI to suspend by left-clicking and holding the power off button until it turns into a pause button, and then I left-click that button. The laptop is docked with two monitors connected and the lid is open (although the laptop screen is not used) when I attempt to suspend it. This used to work until recently. BIOS has not been touched or upgraded. Log excerpt: ...
