Can't get to my problematic system to test at the moment, but do recall seeing that reference and don't think it worked for me. I do know that my system will not boot CentOS 5 with any of the CentOS kernels, but will run on recent Fedora or CentOS 4 kernels, as documented in http://bugs.centos.org/view.php?id=1879 That references upstream https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=186272 There have been boot problems with different Promise controllers with somewhat different symptoms. Mine is 00:11.0 Mass storage controller: Promise Technology, Inc. PDC20575 (SATAII150 TX2plus) (rev 02) Not a RAID controller. What exact hardware are you finding the nodmraid work-around helps on?
