dpkg was interrupted

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

så kör jag "dpkg --configure -a"

och får då ut:

"Setting up initramfs-tools (0.93.4) ...
update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools ...
update-initramfs: Generating /boot/initrd.img-2.6.32-trunk-orion5x
/dev/mtdblock2 is not a block device
dpkg: subprocess installed post-installation script returned error exit status 1"

Har googlat men blir inte klokare Halp
