> Did you do a clean kernel build?
> --HPS

 I am not sure what "clean kernel build" means.
 But, I am regularly doing "cvs update -APd;make buildworld && make installworld && make buildkernel && make installkernel", and I tried it by adding "make delete-old" before make buildworld.  And, yet I have the same result.

 Part of my dmesg is as follows (it is amd64 machine);
