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. So likely there is something e= ssential > going away when rebuilding the initrd. The messages sound like basic = root fs is > not there, so it misses all the mount points. But I admit to be too l= azy 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=3Dy CONFIG_DEVTMPFS_MOUNT=3Dy CONFIG_TMPFS=3Dy CONFIG_TMPFS_POSIX_ACL=3Dy Good news is its working now but certainly my old config did not work a= nymore.
