I am seeing these problems, too. 2.3.36-pre3 is ok, after that, nothing but problems. 2.3.40-pre3 did work most of the time, but hung the system after an suspend-to-disk, resume-from-disk cycle, so I stayed at 2.3.36-pre3. It turns out the TI 1225 in my Dell Inspiron 7500 does not always get an IRQ assigned (ie it gets either irq 0 or 255, instead of 11). This even happens after the boot-up message of the kernel stating it assigned irq 11 to the controller...
Stange enough, when loading the yenta module sometimes gets the irq's right, sometimes it doesn't.
Also, my wavelan IEEE card (16 bit) on some kernels hangs the complete system (no keyboard, mouse etc) when inserted. All is ok again when I unplug the card: keyboard is immediately back, and in the systemlog I see lucent's driver complaining about the card having suddenly disappeared (Duh).
My DLink DFE-660TX (cardbus, 21143 chip) just gets 2 irq's, after that I get messages about TX hung etc, probably because the driver doesn't get any irq's.
And yes, I am seeing "spurious 8259A interrupt: IRQ7" too, but I saw them too in (the working) 2.3.36-pre3.
Hope this helps identifying the problem.
