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?
