The hda: lost interrupt problems and the G3/L2 cache issues are 2
different things.
Is your Sonet card also providing an IDE interface ? In this case, it's
possible that the chipset on this card is not supported by 2.2.18 without
the big IDE patch (which need to be fixed for powerpc).
For the G3, I'd rather figure out the correct L2CR value and "fix" it
from userland (via /proc)
