THANK YOU, GENTLEMEN!!
I thought I'd been around awhile... never recalling hearing of
'partprobe'. I ran it, and have been having a pile of problems with
udev, and partprobe reveals that the system thinks I have this:

[root at iam My Downloads]# partprobe -s
/dev/hda: msdos partitions 1 2
/dev/sda: msdos partitions 1

WTF? 
I have ext3 partitions and lvm on hda... no wonder udev barfs. How do I
safely fix this?? The boot sequence finds ext3 partitions, and
everything gets mounted as such, or so I beleive. Something got
clobbered during yum upgrade... I suspect. Thanks again for your timely
post. Ric
