Sad v3.1.10/11 breaks IRQ use for 3CCFE575

Up to v3.1.8 everything worked fine. Now, with versions 3.1.10 and 3.1.11, my 3CCFE575 card won't work due to 2 devices sharing a single IRQ.

The difference in working/not-working is soley the pcmcia-cs driver version. The kernel (v2.2.14) and pcmcia config are unchanged.

This is the error I get with 3.1.1x:

  eth0: transmit timed out, tx_status 00 status e601.
  eth0: Interrupt posted but not delivered -- IRQ blocked by another device?

Sure enough, there 2 devices on IRQ 11!

This is from v3.1.8:

# cat /proc/interrupts                 
           CPU0                               
  0:       9655          XT-PIC  timer        
  1:          2          XT-PIC  keyboard     
  2:          0          XT-PIC  cascade      
  3:        257          XT-PIC  eth0         
  5:          1          XT-PIC  soundblaster 
  8:          2          XT-PIC  rtc          
 12:          4          XT-PIC  PS/2 Mouse   
 13:          1          XT-PIC  fpu          
 14:      21425          XT-PIC  ide0         
 15:          2          XT-PIC  ide1         
NMI:          0                               

And this is from v3.1.10:

# cat /proc/interrupts
           CPU0                               
  0:      12453          XT-PIC  timer        
  1:        121          XT-PIC  keyboard     
  2:          0          XT-PIC  cascade      
  5:          1          XT-PIC  soundblaster 
  8:          2          XT-PIC  rtc          
 11:          0          XT-PIC  i82365, eth0 
 12:          4          XT-PIC  PS/2 Mouse   
 13:          1          XT-PIC  fpu          
 14:      21343          XT-PIC  ide0         
 15:          2          XT-PIC  ide1         
NMI:          0                               

Any advice on how to get my Ethernet card work with the 3.1.1x drivers?

Thank you.
