It used to work when I installed rawhide last month.

I guess there is no verbose mode?

It does match. Here is the output from dmsetup table inside the rescue
environment.

nvidia_hcddciddp1: 0 409368267 linear 253:0 241038
nvidia_hcddcidd: 0 586114702 mirror core 2 64 nosync 2 8:16 0 8:0 0
VolGroup00-LogVol01: 0 4063232 linear 253:3 83952000

nvidia_hcddciddp2: 0 208782 linear 253:0 63

As a reference here is what is in the initramfs init file:

dm create nvidia_hcddcidd 0 586114702 mirror core 2 64 nosync 2 8:16 0 8:0 0
dm partadd nvidia_hcddcidd

Indeed. And it looks like Jermey Katz just fixed that.

Now if I can get control-c working and ssh/scp able to grab terminal in
the rescue environment my complaints with it will be gone.
