Thanks Tim for building the test kernel, and Hmpf, thanks for testing it and confirming it fixes the problem.

Okay, so the problem is:

Looking at Focal, it seems Tim has submitted the revert and it has been applied for the next kernel update:

Thanks Tim!

As for Bionic, it seems to still be applied to master-next, and hasn't been tagged into a release yet:

Groovy seems to be in the same situation:

Tim, are there any plans to get the revert landed in Bionic and Groovy for this cycle? I really don't want cause any regressions if we can avoid it.
