The patch was applied. These 2 kernels were built from "clean" at the same time.

Look closer it was built Feb 20 09:01:53. Not Feb 2 0 09:01:53.
There is a space between the 2 and 0 because of a minicom linewrap I guess.

"clean" after your patch was applied.

I will do it all again from scratch if you wish.

Not a problem. I am at your disposal. I'm not ignorant when it comes to building
and installing kernels.

Standing by.
