hi marcelo
the same thing as been included in 2.6.5-mm4. here's the 2.4 version.

---snip---
acer travelmate 360 has a broken interrupt routing. there's an interrupt storm
on irq 10 w/o this patch as soon as yenta_socket is loaded. the problem
has been seen on different machines (reported on l-k and on pcmcia-cs
list). there's also an USB controller on the same interrupt line as the CB
which also works fine after the patch. and routing via ACPI fails too.

Hi Daniel,
Could you take a look at my pcmcia problems?
I have a very similar problem enabling a pcmcia firewire card on my Gateway
600YG2 laptop. I am using a Gateway 600YG2 laptop (Intel P4-M, PCMCIA TI
PCI1520 controller)
on 2.4.25. I have 3 different pcmcia firewire cards. When I insert module
yenta_socket with any of those cards, I get "Yenta ISA IRQ mask 0x0a98, PCI irq
0" and "PCI: No IRQ for interrupt pin A of device 03:00.0 please try using
pci=biosirq". After this error, when I run the modprobe ieee1394 and ohci1394,
I get "ohci1394: failed to allocate shared interrupt 10". The same pcmcia
firewire cards work on old Gateway 9300, 9500 laptop and IBM T22 laptop.
BTW, my Netgear pcmcia 10/100mb ethernet card works on the Gateway 600YG2
laptop. Also my USB pen drives are not working too. The bootparameter
pci=biosirq doesn't seem to work.
It worked fine with 2.4.20 without any problems. Could someone help me to fix
this problem on 2.4.25? I have buillt both of 2.4.20 and 2.4.25 without ACPI.
Thanks,
Jin
