>Description:
A kernel using the new MBR handling code will panic due to a division by
zero as soon as "ccdconfig" is used. It doesn't matter if the involved
partitions use the old or the new ID.
To avoid questions:
- I added "COMPAT_386BSD_MBRPART" in my kernel configuration file and
built the new kernel from scratch.
- I updated and installed the new boot code.
>How-To-Repeat:
Try to use ccd(4) with a kernel with the new MBR code.
>Fix:
Sorry, I don't know.
