I've been experiencing a bug in the Fedora kernels for awhile involving the ohci1394 driver. If I include the driver in my initrd (causing it to be loaded at boot time), the IRQ corresponding to my TI OHCI firewire controller is disabled (message says "Disabling IRQ #11", I think due to the kernel irq debug code noticing that it hasn't been handled too many times). Since this IRQ is shared with my pcmcia, wireless, and usb devices (don't ask me why it's wired this way, this is a Toshiba Satellite laptop), nothing important works after the IRQ is disabled. I've reproduced this problem under 2.6.14-rc2, which includes Al Viro's latest fix to initialize interrupt handler spinlock (which I was hoping would fix the problem but didn't). Is this a known issue? Does the interrupt handler need to special case initialization somehow and return IRQ_HANDLED even if there's no event sometimes?
