udev hangs at startup; how to debug?

[Neil Bird]

   After updating a friends FC6 upgrade from FC4, which had gone a little 
awry, I'm left with a system that hangs at starting udev, shortly followed 
by  init killing /sbin/start_udev and then a kernel panic.

   Any ideas how to go about debugging this?


   I've tried noprobe, nousb, nopcmcia, noudev to no avail.  I can currently 
only get in via the rescue-boot off the install DVD.
