I've finally figured out how to get an error message, but I have no idea of how to fix it.
By removing "rhgb" and "quiet" from the grub commandline, I see a whole bunch of write-up going by, then there is a several-second pause, and then this:
dracut warning: no root device "block:/dev/mapper/vg_ws194-lv_root" found
After that I get the kernel panic message and that's the end of the line.
By booting the machine from the rescue cd, I can find /mnt/sysimage/dev/mapper/vg_ws194-lv_root, which is a symbolic link to ../dm-0
/mnt/sysimage/dev/dm-0 exists.
lvscan tells me this: ACTIVE '/dev/vg_ws194/lv_root' [50.00 GiB] inherit
lvdisplay shows a bunch of stats about /dev/vg_ws194/lv_root that look normal to me.
In summary, it looks very much like vg_ws194-lv_root is indeed present and accounted for, but dracut didn't find it for some reason.
