interrupt trouble

Hello,

I have been having troubles getting the prism54 driver to work
with a Netgear WG511 card on Mandrake 10.0 (4GB-2.6.3.15mdk).
There appears to be some type of interrupt problem that trashes
my wired interface (natsemi driver).  Here is what I have been
able to determine so far:

1.  If I insert the card after booting, I get an IRQ11 that no one
     responds to & then IRQ11 gets disabled (which is the natsemi
     driver).  In this case "iwspy" does not show eth1 (prism54)
     at all.  Excerpts of /var/log/messages is attached (IRQ11.txt).

2.  If I boot with the card installed, "iwspy" does show eth1,
     but "iwlist eth1 scan" says there is nothing to report.

3.  I tried the following command sequence & got some bizarre
     results:

       > rmmod prism54
       > dmesg -c > /dev/null
       > modprobe prism54
       > dmesg -c | tee output1.txt

     The resulting output1.txt file is attached.

There is obviously some kind of interrupt problem.  Can you tell
if the problem is the prism54 driver or yenta conflicting with
the natsemi driver?  The interrupts.txt file is the contents of
/proc/interrupts when booted with the WG511 installed.

Thanks for your help.  This has been frustrating.
