| When a disk attaches offline, the wedge discovery routine
| previously failed and reported errors.
It did, yes - would have been nicer to suppress the error message
for such an ordinary event, but aside from the noise, it was harmless.
| Now it is simply skipped with the same result.
Not quite the same - previously once the drive was ready, wedge
discovery would happen - not just "a few milliseconds" but up
to many seconds later in some cases (depending upon the drive).
I have never looked to see the mechanism by which that worked,
I always assumed that the drive sent some form of "now ready"
message/interrupt when it became ready, but some form of polling
from the kernel might also have been a possibility.
I also don't know whether it depended upon the drive (though I
have quite a few quite different types, and all acted the same in
this regard) or the particular controller chip (less variety of
those in my system).
