I so for some days two new patches. Thirst one may help you ( pcmcia: irq probe can be done without risking an IRQ storm):

Requesting the shared irq line from another driver result in a spurious interrupt storm which finally disables the interrupt line. I have seen similar behaviour on resume before (the hardware does not work anymore so I can not verify). Change the spurious disable logic to increment the disable depth and mark the interrupt with an extra flag which allows us to reenable the interrupt when a new driver arrives which requests the same irq line. In the worst case this will disable the irq again via the spurious trap, but there is a decent chance that the new driver is the one which can handle the already asserted interrupt and makes the box usable again. Eric Biederman said further: This case also happens on a regular basis in kdump kernels where we deliberately don't shutdown the hardware before starting the new kernel. This patch should reduce the need for using irqpoll in that situation by a small amount.
