irq 19: nobody cared

[JD]

Kernel-3.7.0-rc6.git local build, belched out
[90658.498609] irq 19: nobody cared (try booting with the "irqpoll" option)

irq19 belongs to my Atheros AR-5008 mini-pci card.

This problem does not occur on kernels prior to 3.7.
Every time it happens, the card gets stuck in a mode
that renders it unusable, so that even restarting wpa_supplicant
does  not restore association with AP. Only a reboot
fixes the problem until it happens again.

Is there a user util to force a soft reset of a mini-pci wifi card?
