Yeah, that's how I started my own configs for 2.6.34, then I always use make localmodconfig to trim crap down. In this case my config just stopped working on newer kernels. What cured it was I took Daniel J Blueman's 2.6.35 ubuntu package: http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-2.6.35-9-generic_2.6.35-9.14_amd64.deb Then stole that config and used it as a starting reference, then did the localmodconfig after booting into it and cp'ing that config to my own and running oldconfig. > I think to remember make modules_install purges all existing modules under > kernel before installing the new ones.

But I admit to be too lazy to walk > all the config. Right, I thought it was the rootfs, the rootfs is provided through the tmpfs filesystem which both configs have. They also have devftmpfs. This is why I started to suspect something on the distribution side but low and behold linux-image-2.6.35-9-generic_2.6.35-9.14_amd64.deb worked well. CONFIG_DEVTMPFS=y CONFIG_DEVTMPFS_MOUNT=y CONFIG_TMPFS=y CONFIG_TMPFS_POSIX_ACL=y Good news is its working now but certainly my old config did not work anymore.
