New Kernel -> Can't read device /dev/hda


So I just compiled a new kernel with the 2.6.9 sources on my ubuntu system (5.04). And for some reason, on boot up, it says

device mapper: error adding target to table
device mapper: dm-linear: device lookup failed

about 5 times. All partitions on /dev/hda are no longer readable when booting up under this kernel. There is a fat32 one, and a freeBSD UFS. The system is on /dev/hdb, and the ntfs partition located on it is still readable.

Any ideas? I'm totally lost

just a a guess

Is there any chance you are using Reiserfs?

From what little I know of the 2.6 series, it requires that you select reiserfs during kernel configuration.
Without selecting it, you will not see it.

thanks for the response

Actually, it turns out that evms was causing conflicts, so a simple uninstall did the trick
