This patch (as1003) changes uhci-hcd to treat the URB_ISO_ASAP flag
the same as other host controller drivers, namely, to schedule an Iso
URB for the first available time slot that hasn't already expired.
URBs in which the flag isn't set will be scheduled for the first slot
following the last URB, even if it has expired.
This fixes a problem reported by Martin Bachem.

the NULL dereference is here:
(gdb) list *0xffffffff804a9504
0xffffffff804a9504 is in natsemi_poll (drivers/net/natsemi.c:717).
712 return count;
713 }
714
715 static inline void __iomem *ns_ioaddr(struct net_device *dev)
716 {
717 return (void __iomem *) dev->base_addr;
718 }
719
which is this code from natsemi.c:
2227 struct net_device *dev = np->dev;
2228 void __iomem * ioaddr = ns_ioaddr(dev);
2229 int work_done = 0;
seems like the NAPI changes in -rc1 added an np->dev field but forgot to
initialize it ...
does the patch below fix the oops for you?

[NET]: Make NAPI polling independent of struct net_device objects.
added np->dev to drivers/net/natsemi.c's struct netdev_private, but
forgot to initialize that new field upon driver init. The result was
a predictable NULL dereference oops the first time the hardware
generated an interrupt.
