Ok, found the issue: a kernel will only boot in Lucid if devtmpfs is compiled in. Just setting the following in my .config results in a successful boot:
CONFIG_DEVTMPFS=y CONFIG_DEVTMPFS_MOUNT=y Just to repeat: this is a change that occurred late in the lucid development cycle; before then, devtmpfs was not necessary. I don't know if making devtmpfs mandatory was a deliberate move or just accidental, so I'll leave it up to someone else to decide whether to close this as INVALID or not. Personally, I've got no objection to enabling devtmpfs so I'm happy now. -- cannot boot custom kernel with no initrd https://bugs.launchpad.net/bugs/575666 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
