Brain idiocy on my part. I couldn't figure out why this kept panic'ing for ccdconfig when I hadn't config'd ccd in. It turns out there *are* .ko modules in /modules- they're way out of date because the interfaces changed. phk rev'd the kernel version, but that didn't stop the modules from loading. Somebody file the appropriate bugs. On Mon, 5 Jul 1999, Steve Price wrote: > To followup on my own post I rebuilt a kernel with debugging > symbols and DDB.
