Good morning! I know I'm on the bleeding edge, but I'm having trouble getting the 2.6.30-rc5 kernel to boot on my CentOS 5.3 box. It's a dual-socket Nehalem box with the Tylersburg chipset (Supermicro board). I installed CentOS 5.3 on it with no problems - boots and runs fine. But I wanted to take a look at the 2.6.30-rc5 kernel and try out some new stuff. After a few go around's with 2.6.30-rc5 the closest I can get it to boot is that I receive the following typing from my notes, so please excuse my typos): Red Hat nash version 5.1.19.6 starting insmod : error inserting '/lib/dm-region-hash.ko' : -1 File exists Reading all physical volumes. This may take a while... Volume gruop "VolGroup00" not found mount: could not find filesystem '/dev/root' setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory setuproot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! I think this all boils down to the missing module. But I can't seem to find it in the 2.6.30-rc5 kernel. Any ideas? Thanks! Jeff
