The rootfs entries are interesting. I believe they are used by initrd, 
but should be overwritten by proper /dev entries later in the boot process.

So the kernels see the partitions, but .33.3 doesn't have the device 
files. Then I think there's some problem with udev. Check the output of 
"udevinfo --export-db" with both kernels to know if udev sees your disk. 
Also see if you can find your partitions in /dev/disk/.
