>Description:
After having "cvsup'ed" (980323, src-sys only), and rebuild the kernel,
when booting the new kernel, it fails to mount the root (/).
The new kernel loggs `changing root device to sd0s2a' after a few lines
it loggs `/dev/sd0a on /: Specified device does not match mounted device'
and the startup procedure is terminated (enter path to shell or press enter for sh)
Tested to boot up the working kernel.old, and it loggs `changing root device to sd0a,
and starts up OK.
NOTE: No "config" files has been changed between the two kernel versions.
