I just rebuild the sparc kernel.  In addition to TDR2, I add KERNFS,
SYSVMSG,SYSVSHM,SYSVSEM and SHMMAXPGS.  Then I use config.new to configure
the new kernel.  When I reboot by the new kernel, it works fine at first.
When it found the boot device is sd0 and panic with sema is NULL.  What
is wrong?
