But guess that this is a more appropriate list to ask for help on. After failing to get 2.6.17-rc6 working on a HP dc7600U I went back to 2.6.16.20. It also fails to find any volume group during boot. I think this might be problem with SATA as I can boot the same build on two other systems that have IDE disks. I get success on VIA Epia M10000 and a P4 Shuttle systems that use IDE disks but fail on the HP dc7600U that uses a SATA disk. All three systems use LVM2. The Fedora build of 2.6.16 works on all three systems. I'm going to see if there are debug messages I can turn on it libata and md that might give more information. Any suggestions as to what I can do to track down this problem? Barry
