Resume sleep from USB problem

Postby otyugh » 2019-12-12 20:54

Hey,
I've got 10 PC recovered from trash (DELL PCs : Optiplex 755) ; for the most part, everything works on Debian stable (buster). But there is something weird with the suspend mode. When suspended, there is no way to wake up the PC from either the mouse or keyboard (even if pushiing on the buttons make a light blink in the keyboard ; the PC doesn't wake-up).
The only way to do it, is to presse the power button once, then it wakes-up alright.

Maybe it's a motherboard issue, or something to change in the BIOS ? Seems not :
I tried randomly to boot on Ubuntu 18.04 : to my surprise suspend could be resumed from the keyboard.

So I wondered :
- Maybe it's a nonfree firmware issue ? I tried to install them all. Reboot. Nope, all the same.
- Maybe it's the kernel version ? I tried a downgraded one from stretch. to use the latest one from buster-backports, and even the Ubuntu18.04 one ; I did not see any difference, wathever linux-image I tried (I checked with "uname" to check if I was using the right kernel every time).

I'm out of ideas.

There is my dmesg, if it can help ?
