Comment 9 for bug 1552551

I have bisected the source of the bug, then took a brief attempt at a fix, unfortunately the quickie fix failed (bad CONST definitions in an .h file). I thought perhaps it was some kind of memory region locking error causing corruption, but it appears to be more complicated than that.

The bad commit is b836439 - 4KB Sector Support.
The previous good commit is 2f5d1f7.

I'm having difficulty integrating this compiled kernel into my PXE environment, hence the week long delay in posting this, unfortunately I lowered my priority for the whole issue once I figured it was too late to get anything into the new LTS release first run and it's been marked as expired. christopher.m.penalver said to mark as Confirmed, but I don't know if I can do that myself, or if I can do anything at all at this point other than post this info here for anyone who's interested.

If I do ever get time to look at the (significant) code changes for the 4K support, I'll post changes here as well?
