Anil, Robert,
Please try the following patch. We don't understand the reason why
this "block 3015" problem is becoming so common now where it didn't
appear before; something must have changed, but in any case, the
following ide-tape patch should work around it.
Andre, please include it in one of your 2.2.15 patches, to avoid
repeated reports about it.
Cheers,
Gadi
