2.4.20 - yenta, i82365 PCI / ISA irq problem

Hi there,

for quite some time now, I'm fiddling around with an annoying problem on my Fujitsu-Siemens S6010 laptop together with a Dell TrueMobile 1150 WLAN mini PCI card (orinoco chipset). Searching both the pcmcia_cs and orinoco mailing list archives pointed to a deeper, irq related problem. Excuse me if this is still the wrong forum, but probably someone out here may have some clue.

So here we go - Booting with in-kernel pcmcia gives the following output:

Well, in both cases three sockets are recognized and the WLAN card behind the cardbus bridge on the mini PCI is also correctly detected, but there seems to be a problem with either the shared PCI IRQ 11 or the ISA IRQs of which none seems to be available for socket 2. I gave the i82365 different irq_mode options, but this didn't change anything.

A removable PCMCIA WLAN (also orinoco based) in socket 0 works perfectly. There is no physical slot for socket 1 on this laptop.

Here's lspci -v for the cardbus controllers:

I'd appreciate any hints on how to proceed from here and hopefully find a solution.

TIA and best regards ... Michael Ulbrich

I had lamost the same problem with my CPQ Presario. Time to time the card did not get the IRQ (RequestIRQ: Resource in use). I have a patch that fixes that on my machine at home. If you want tomorrow I'll post it.
