Comment # 13 on bug 1187329 from Lee Duncan

I went through all 30 of the pm80xx patches that were added (by me) to
SLE-15-SP3, to see if I incorrectly applied any of them, but I found no
differences.

I sent through the diffs you supplied to see if any new printk()s were added
that were not protected by debugging mode, and there were none.

Are you sure your hardware hasn't developed an issue? Is there any way you can
try a replacement disc?

Also, a crash kernel dump would help track down where the code is actually
dying.
