One common problem I saw with the original netconsole patches was that the low level drivers' poll function was grabbing the driver spinlock, but the driver would otherwere do printk with the spinlock hold (->easy deadlock)
Does your patchkit handle that?
I worked around it in some drivers by not grabbing the lock in the direct access poll path, but it's a bit ugly.

P.S.: Also what would be really nice for netconsole would be "kernel ifconfig" similar to what the nfsroot code does. With that it would be actually possible to use it as a full console replacement. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
