Compared to lenny release kernel, 2.6.28 is a much better choice. Also Debian stays with old ide drivers to make updates more easy which I don't like at all. One of my nic needs an update to r8169 driver, which does not work up to 2.6.27, so no way for network install lenny...
No announcement yet.
Ubuntu 9.04 Will NOT Ship With The Linux 2.6.29 Kernel
