Comment 36 for bug 1541082

@ernst:

Many, many thanks for the details . . . I can see numerous "errors" showing
up as the OS loads, including something about the "r128" "failing," I think
we've discussed some of these things before . . . but, since for the most
part "things were working" I didn't mess with it.

But, indeed, very easy to test out your suggestion for the r128 module . .
. and then see what happens. I did check the "Display" stats in the
Control Center and it seemed like things were showing "OK" . . . but,
didn't do any "lsmod" checks, etc.

Might be able to get to that tomorrow . . . I'll post back if and when I do
. . . . Again, appreciate the time you spent on this . . . .
