[SPARCbook] Sparcbook3 and y2k patches...

[The UnSeen]

I performed a clean installation of Solaris 2.5.1 and NCE and am
attempting to install both the Recommended and Y2K patches from Sun.
After completing the patches the sparcbook3 fails during the reboot
attempting to load the sd driver:

/platform/Tadploe_S3/kernel/drvg/sd: undefined symbol ddi_select_sr_device
/platform/Tadploe_S3/kernel/drvg/sd: undefined symbol ddi_register_sr
/platform/Tadploe_S3/kernel/drvg/sd: undefined symbol ddi_register_sr_dump
sd error doing common
Connot load drivers for ...../sd at 3,0:a
Cna't load the root filesystem

When I reboot from cdrom, all looks ok.  Both the filesystems and disk
partition table look and work fine...

Any insight?
