There seems to be a lot of code in the IDE subsystem relating to
interrupts. Is there a way to set a device in polled (i.e.
non-interrupt) mode? Maybe some way to run the tasklet/bh periodically?
Does the IDE system want to monitor my ATA device's Ready_NotBusy
interrupt?

No, linux IDE layer can't do that in a sane way, you are asking for
a _lot_ of trouble... (especially if doing DMA)

"No" there isn't a way to set the device into polled mode, or "No" it
doesn't monitor the Ready_NotBusy interrupt?

Can't you use the Ready_NotBusy interrupt as IDE interrupt?

I am currently debugging a problem with an in-house developed PCI Bus Master
card on a Pentium 4 machine. I saw something that surprised me that I
thought you might be able to shed some light on. I noticed that my ide1
device (cdrom) is constantly generating interrupts (as per
/proc/interrupts). The device is mounted, but there is no CD in the drive,
nor am I directly accessing it. What is causing these interrupts? I
thought it might be because APM was enabled, so I added apm=off on the boot
line an re-booted. However, it still is generating lots of interrupts. The
section of boot up messages related to the ide stuff is below. I also
included info resulting from hdparm -i /dev/hdc.
Thanks in advance for your help.

Hi,
I'm not sure about this, but I suspect it to be related to
automount/autofs or some other daemon-like process that's trying to be
too helpful. Find out how to disable that (listed in logs below)
and see if it stops.
