I have a system running linux 2.6.26.3, with the ext3 filesystem. I'm trying to upgrade the system to the linux 2.6.33.2. The older linux kernel used /dev/hda# device to access the filesystem. The new kernel is using /dev/sda# to access the same filesystem.
When I boot using 2.6.33.2, the filesystem seems to be recognized and mounted fine, but e2fsck fails. Here is some of the boot logs:

/sbin/e2fsck: No such file or directory while trying to open /dev/sda3
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
/sbin/e2fsck died with exit status 8
Now, if I revert the kernel back to 2.6.26.3, the same file system passes e2fsck just fine. I'm running e2fsck 1.41.4 in both cases. Any thoughts? Does this have anything to do with the sda# vs hda#?
Here is the similar log, when the system comes up ok with the 2.6.26.3:
[ 4.692983] kjournald starting. Commit interval 5 seconds

Any help would be greatly appreciated.
Thanks,

UPDATE: I figured out the issue. I was missing the actual devices in the /dev/. I created the devices sda1-4 in the /dev/, and the e2fsck is happy now!
