I have the same(?) issue. Root (ext3) located on /dev/sda5, which is a non-raid sata disk. Problem first occurred in 2.6.10-1, still here on 2.6.10-2. I'm running the k7 flavour. Nothing happens when selecting the 2.6.10 kernels from grub. The last thing that draws on my screen is "Starting Ubuntu" - after that nothing happens. 2.6.9-1-k7 runs fine, and here's relevant(?) output while running it: Output of lspci: eruin@ubuntu:~ $ lspci 0000:00:00.0 Host bridge: VIA Technologies, Inc.
