Hi! I've discovered an interesting bug in `npx' driver in an old version (2.2-SNAP of spring 1996). When it is the last device that adds its kdc_* information at boot time and then later some device tries to add it information when the system is running (for example in result of `scsi -p' command) it remaps the npx driver code to some empty page. After I found this reason of panic I checked -current and found that npx just has no kdc_* structure anymore ! Did someone else found these panics before me or is it just a coincidence ? In the last case I think the bug may reappear in some other driver. -SB P.S. I've found that `vtophys' is worth adding it to DDB. The addition is very simple. Does anyone from the core team think that it's worth too ?
