The rocketport supposedly does't use interrupts at all. At least, that's
what the driver, documentation, and hardware manual claim.
I did move the wd card to several other irq's, with the same results --
crash every time. It doesn't seem to be related with the irq number at all.
Is it possible the rocketport driver is stomping on internal kernel
structures? Or simply interacting with the network drivers in a strange way?
This thread seems to be straddling both the linux-serial and linux-net
topics, since the problems seem related to both. What do you think?
