Comment 14 for bug 1910866

OK, so using https://people.canonical.com/~kernel/info/kernel-version-map.html that states that Ubuntu kernel 5.8.0-36.40~20.04.1 matches mainline version 5.8.18. I have installed 5.8.18 and it fails ! So it is not the Ubuntu patches.

Ubuntu Kernels:
linux-image-5.4.0-59-generic: PASS
linux-image-5.8.0-36-generic: FAIL

Mainline Kernels:
linux-image-unsigned-5.8.18-050818-generic: FAIL
linux-image-unsigned-5.11.0-051100rc3-generic: PASS

I'll see if I can find where it changes from FAIL to PASS between 5.8.18 in the mainline kernels. Please advise if should also/instead compare between 5.4 and 5.8.18 :-)
