SubjectRe: Can't burn DVD under 2.5.59 with ide-cd

Joerg,

Then you are aware of the push/pull by one bit as linux does not set a
reserved place holder for bit0 in the status byte. I have to agree with
you that it stinks and make decoding status codes messy when supporting
N-interfaces of the protocol.

Cheers,
