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.
Thanks,
Larry

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.
Best,
Dominik

It worked fine in 2.6.37 and is a regression. The bug is #40362.
I tried to bisect between 2.6.38 and 2.6.37, but didn't really get anywhere. As
noted in the bug report, 38 and 39 lock the computer when I plug in. Only 3.0
comes back with the nobody cared message.
