This is on a 3ware 9500s-12 using the twa driver on 1.3.7-PREVIEW. If you grep the source, you will find that very few of the disk controllers set dev_t->si_iosize_max, so you will almost always get these warnings from these controllers in kern/kern_physio.c::physio.

Back to my original point, the minor is printed in hex if the device does not have its name set, as can be seen in kern/kern_conf.c::devtoname. Is this similar the si_iosize_max problem? Are some drivers simply incomplete, and not setting the device name as they should?
