Help: eth1: IRQ handler is looping too much! Shutting down

Making progress, but sure could use some more help -- I'm stuck:

Redhat 7.2/2.4.18, pcmcia-cs-3.1.34, Orinoco Gold 7.28, Orinoco 11b.

Upon bootup, dmesg shows:

Linux PCMCIA Card Services 3.1.34

eth1: Station name "HERMES I"
eth1: ready
eth1: index 0x01: Vcc 5.0, irq 11, io 0x0100-0x013f

When I issue "iwpriv eth1 monitor 1 1" dmesg appends:

eth1: IRQ handler is looping too much! Shutting down.

Thinking it's an IRQ problem, I've tried each line (uncommented) in the
following /etc/sysconfig/pcmcia:

#PCIC_OPTS=irq_list=3
#CORE_OPTS=
#CARDMGR_OPTS=
#PCIC=yenta_socket
PCIC=i82365
#PCIC_OPTS=irq_list=11
#PCIC_OPTS=irq_mode=0
#PCI_IRQ_LIST=3
#PCIC_OPTS="irq_mode=0 pci_csc=0 poll_interval=100"
#PCIC_OPTS="irq_mode=1 irq_list=3,4"
PCIC_OPTS="irq_mode=0 pci_irq_list=3,4,5,7,9"

Interestingly, the ti1410 always gets irq 11 -- nothing I do can seems to
change that.

Although, when I choose irq_mode=1, I get the following:

  TI 1410 rev 01 PCI-to-CardBus at slot 01:0c, mem 0xe4801000
    host opts [0]: [isa irq] [pci irq 11] [lat 64/176] [bus 2/5]
    ISA irqs (scanned) = none!<6>    PCI card interrupts, PCI status changes

Does the group think this looks like an IRQ conflict?  If not, what then?

Thank you!
