Subjectstrange 1.2.13->2.0.n cdrom driver problem
Date
Hi,

My cdrom driver is experiencing bus read problems during heavy
ide-disk i/o. (Typical debia `dpkg --install', so i guess some tar
-zxf)

Strange thing is that the 1.2.13 version of the driver (under 1.2.13)
does not show these problems. pre2.0.7 and later do show the same
problems (up to 2.0.7, at least). I tried the _same_ driver code that
worked under 1.2.13 on the 2.0.7 kernel, gives the same problems.
I spent the whole day debugging. It appears that some bus reads are
missed, maybe an interrupt is not coming through, due to the
ide-activity.

Does anybody know what major interrupt-code changes appeared between,
say, 1.2.13 and 2.0.7?
