I just tried UML with the new 2.6.25 kernel but it would not boot up
properly. I was using the same rootfs with 2.6.21.3 and it worked fine.

I used my old .config from 2.6.21.3 and did 'make oldconfig ARCH=um' and
accepted the defaults for any new option. I have CONFIG_EXT2_FS=y and
CONFIG_EXT3_FS=y so thats not the issue. Usually that error means some
other process locked the filesystem but fuser reports no other processes
using them. I probably forgot to set something up, but I don't know what.
