I downloaded the stock 2.6.22.5, but the cow functionality is still not working as described in the User-mode HOWTO at http://user-mode-linux.sourceforge.net/old/UserModeLinux-HOWTO-7.html#ss7.2 Specifically, with this kernel, I can boot with "ubda=cow_file,original_file" - however, if I subsequently attempt to boot with "ubda=cow_file", I'm getting the same panic in cowify_req: [...] Initializing software serial port version 1 ubda: unknown partition table kjournald starting. Commit interval 5 seconds EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly.
