Problem with ide-cs

With kernel 3.0, my external hard drive attached to a PCMCIA card reports "irq 11: nobody cared (try booting with the "irqpoll" option)". The driver in question is ide-cs. When I try irqpoll, the device works correctly. Naturally, the interrupt is shared with yenta, the PCMCIA adapter driver. In addition, that same interrupt is used by a BCM4318 Cardbus device.

I plan on preparing a Bugzilla entry for this problem, but I'm not quite ready. What I would like to know if there is any documentation on what kinds of changes are needed to fix the problem.

Let me guess: it worked fine in 2.6.39, or .38? Output of "lspci -vv", "dmesg" for a working and a non-working kernel would be good starting points for trying to debug this issue.
