Can't boot after yum update -- "Read-only filesystem"

Description of problem:
I just updated from FC2 to FC3-Test1 (actually, to the Fedora development RPMs).
I now get several errors after booting, saying that services can't be started because the filesystem is read-only.
Eventually I get a terminal login prompt. "cat /etc/mtab" says that "/" is mounted "rw", yet nothing can be written to it. I don't know how to try to unmount it and re-mount it in rw mode, since it is the root filesystem.
Any help, as soon as possible, would be greatly appreciated please -- I just rendered my primary machine useless :-|
Version-Release number of selected component (if applicable):
Steps to Reproduce:
(Upgrade to Fedora-development RPMs)
Interesting tidbit: booting from Arjan's kernel-2.6.7-1.471 has no
problem; booting from Fedora-development kernel-2.6.7-1.488 does not work.
...so I do have a working system now -- thanks. I left the ".488"
kernel in there, so I can run any tests you need me to to trace the
source of the problem.
What's the output of dmesg after booting 1.488?
Does 1.49x work better?
Unfortunately, 1.488 now boots fine, so I can't run dmesg. I don't
know what fixed it. Perhaps booting into Arjan's kernel somehow reset
some erroneous state in a file somewhere. It is odd though that mtab
said "rw" but the errors I was getting said the partition was mounted
I did skim through the dmesg output originally when I had the problem,
and I didn't see anything suspicious, but I may have missed something.
As I can't duplicate the problem currently, feel free to close this
bug report if it is no longer useful.
OK, closing for now.
