Ubuntu 20.04, Lenovo Thinkpad E495 (AMD chipset/graphics)
This laptop frequently won't wake up after sleep, although the LEDs in the lid and various buttons are lit. It's connected to a Lenovo docking station through a USB-C cable, which also has an external monitor attached. When the issue occurs, we are forced to hold down the power button and do a cold boot. Removing the docking cable does not help. Both screens (internal + external) stay blank.
Does anyone have the solution for this?
We have now tried updating the kernel from 5.8 to 5.11, as some posts seem to indicate that the kernel version plays a role in this - can anyone confirm?
