The ne2k thing seems to be the _most_ affected one, as far as I can tell.
However, it could easily be a matter of timing - for example, if the driver does something to trigger an interrupt _just_ before (or after, considering the asynchronous nature of writing to the IO-APIC) doing the enable_irq(), then..
I'm also nervous about the complete lack of locking in vortex_timer(): disabling interrupts doesn't mean that transmits couldn't be pending. But maybe the hardware is ok with changing status concurrently.
