I've reinstalled FC3 on one of my toy machines, and all the sudden udevstart (called from start_udev script) started to core dump during boot.
Checked bugzilla (should have gone there first). Workaround is to upgrade kernel to kernel-2.6.9-1.724_FC3.
For details see bugs 139989 (udevstart segfaults) and 139923 (kernel IDE).
