Ubuntu drivers eating a lot of CPU. Not always but at least 50% of the times
I have actually a very slow PC because of this:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1541 root 20 0 2343424 51804 2624 S 111.9 1.4 198:49.14 DisplayLinkMana
in other words, DisplayLinkMana(ger) eats a lot of CPU. from 50 to more than 100%
sometimes not.
I think this is an issue, that should be fixed.
Thank you.

This affects me as well. Can we get some kind of answer regarding this problem?

Affects all Ubuntu workstations in my team. Prevents their machines from doing useful work e.g. running Docker. This is a pretty ridiculous turnaround for such a critical bug. Do you update the Linux drivers, or are they vaporware at this point?
