Hi, the reason -43 was in -proposed for a short amount of time was that
it contained an emergency fix on top of what was going to -41. The -41
kernel had already gone through the normal SRU process and thus
extending the SRU cycle would be extraneous. We believe the original
breakage occurred before this version and wasn't detected until this bug
report was filed.
