Your hack is working for me. I got message:
"IRQ storm detected on IRQ 11. Disabling"
and everythink works OK. Spinlock was unlocked, procedure
setup_irq() ended and PCMCIA package works fine...
It is possible to add your patch to the kernel?
But I don't know, what device asserted IRQ 11 to start the IRQ
storm... When I was in the function setup_irq(), I installed the
first routine to work with IRQ 11 in its IRQ queue...
Or maybe will be safe to disable concrete IRQ, when is installed
a new handler for it?
I'm sorry, I'm not kernel programmer at all, I still thinking
about it... Maybe will be my think usefull for you...
