Same problem on both 2.6.8-1.610 and 2.6.8-1.624. Kernel 2.6.8-1.541 (default on FC3-T3) works fine. I have tried running mkinitrd with both 610 and 624, and although it produces a different (according to diff) initrd-file than the one created on install it will not boot. Installation of kernels through yum and up2date. Version-Release number of selected component (if applicable): kernel 2.6.8-1.610, kernel 2.6.8-1.624 How reproducible: Always Steps to Reproduce: 1.

You need a root=LABEL=/1 (or similar) on the 'kernel' lines.
Ouch, silly me. Now it works (although hal-0.4.0-2 seems to bug out on the new kernel, but that is another bug) so please close this.
