I tried the hammer and the problem persists.
observer@bbb:~$ cat /proc/cmdline
root=UUID=8b3c3666-22c3-4c04-b399-ece266f2ef30 ro noapic quiet splash
However, I reserve the right to try the hammer again in the future.
When I look at /proc/interrupts without the APIC:
observer@bbb:~$ cat /proc/interrupts

I do not even see the device that I registered unless it is that
r128... line. However the code printed out in /var/log/messages:
Nov 22 16:05:27 bbb kernel: [ 104.712473] apc8620: VID = 0x10B5
Nov 22 16:05:27 bbb kernel: [ 104.712486] apc8620: mapped addr = e0bd4000

(0xe1083e40) on irq (10) and status (0x10)
which indicates it successfully registered without being shared. When
I have more time, I will changed the code to be a shared IRQ and try
the noapic again.
However, without the noapic /proc/interrupts looks like:

I have attached the kernel module. The apc8620 is an IndustryPack
carrier card. I can therefore open up N (in this specific case 5) sub
memory windows in the memory mapped PCI address. The kernel module
keeps track of the slot offsets from the memory mapped address so that
the user can simply use read and write instead of a zillion ugly ioctl
calls. Because the kernel module tracks the slot offsets, I place acp
state into the private data of the file pointer. There can also be
multiple carriers on the bus. So, the array in the kernel module keeps
track of the card specific details with the file pointer the slot
specific information. Both are the same structure (bad on my part I
know but I never intended to show my dirty underwear). To get data
from interrupts (asynchronous IO) I was using readv. Now I am using
aio_read and had to make some minor changes that you will see comments
about to accomidate the change.
Just noticed that r128 is not the carrier card...
Thanks for all of the help so far and I hope this information is helpful.
I almost forgot. I also attached the dmesg output and will try the
irqpoll as it suggests. It is just the IRQ 16 is not the one I am
looking for, but is probably related to my mxser problems that I will
get to later.

On with the detailed technical information. I developed a kernel module

now I am trying to move it to 2.6.22. When I began the to move to
2.6.22, I changed all of the deprecated calls for finding the card on
the PCI bus, modified the interrupt handler prototype, and changed my
readvv/writev to aio_read/aio_write following
http://lwn.net/Articles/202449/. So initialization looks like this:
Hi Al,
From the sounds of it, you might have an interrupt routing problem. Can
you describe the machine you have this plugged into? Possibly attaching
a copy of "dmesg" and "/proc/interrupts"?
Feel free to attach the driver source to your email if the size is
reasonable (which it sounds like it is.)
As a "big hammer" in case it is an APIC problem, please try booting the
kernel with the "noapic" parameter.
cheers,
Kyle
