OK, bypassing the yum reinstall errors,I simply booted from a f21 live
image and fsck-ed the whole drive, then booted up the last working
kernel and removed all the kernel*3.14.27*.rpm packages, rebooted,
did yum update and it installed the newer kernel, did a reboot and
find we're in business. sopmething mjust have failed in the original
install (whenit hung, for whatever unknown reason) and it took the
remove/update pair to be run to clean it up.

thanks for helping clarify things in my (weak,apparently) mind!
