Thanks for the quick reply. It seems that my patching was incorrect. I did not get the device-mapper option in menuconfig. Not sure if you are aware of Debian's make-kpkg program, but here is the command I used to construct my (apparently not very well) patched kernel: make-kpkg --added_patches=xfs,device-mapper --config=menuconfig kernel_image modules If anyone sees an error in this please let me know. If I was to bypass the make-kpkg method of adding patches, what would be the command to apply the patches directly? PS I do not have an /etc/lvm/config. I do have /etc/lvm/lvm.conf - is that what you meant? It looks like the default is to allow all /dev/. I think I have a mispatched kernel - that's my guess.
