Yenta CardBus disables IRQ on insert

[Mike Cumings]

Hi Dominik,

As requested, a full /proc/interrupts with the wired LAN card
on 2.6.11-rc2 (with args):

           CPU0
  0:     162646          XT-PIC  timer
  1:        417          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  5:         12          XT-PIC  uhci_hcd, ESS Maestro
  9:         11          XT-PIC  acpi
 11:          5          XT-PIC  yenta, yenta
 12:        110          XT-PIC  i8042
 14:       2512          XT-PIC  ide0
 15:         30          XT-PIC  ide1
NMI:          0
ERR:          5


After actually using the ethernet device (dhcpcd eth0), the device
added a handler as follows:

 11:          8          XT-PIC  yenta, yenta, eth0

The process I followed was:
1) Boot 2.6.11-rc2 with args.  No cards in slots.
2) Capture /proc/interrupts and dmesg
3) Insert wired LAN card into slot.
4) Capture /proc/interrupts and dmesg (These are those above)
5) Insert Wifi card into slot
6) Capture /proc/interrupts and dmesg

At this point, Wifi was working.  One of the statistical anomalies that I
wish was more frequent! :)

7) shutdown -r now
8) Boot 2.6.11-rc2 with args.  No cards in slots.
9) Insert Wifi card
A) Capture /proc/interrupts and dmesg.

The output from step #A is:

           CPU0
  0:      93073          XT-PIC  timer
  1:        217          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  5:         12          XT-PIC  uhci_hcd, ESS Maestro
  9:         12          XT-PIC  acpi
 11:     100001          XT-PIC  yenta, yenta
 12:        554          XT-PIC  i8042
 14:       2492          XT-PIC  ide0
 15:         30          XT-PIC  ide1
NMI:          0
ERR:          5

and the relevant parts of dmesg:
