There is an rd.md.uuid= parameter, so that's good.

OK so yeah, it's basically not finding rootfs. 29 seconds later...

So now it's found, I'm gonna guess this is your manual attempt at
starting up the array?

What do you get for cat /proc/mdstat at the dracut prompt before you
do anything else? And also the results from

mdstat -E /dev/sda1
mdstate -E /dev/sdb1
blkid

These can be redirected to fpaste or a file. If you have network
access this early it's easiest to redirect to fpaste but I'm not sure
if it's in the initramfs.

From your mdadm.conf, you have UUIDs that do not match what's on the
command line.

cmdline:
rd.md.uuid=5a1848ce:cff64c1f:a622dc1f:e5f06d55

mdadm.conf
UUID=c45384af:aa8fc7ca:7eebaeb8:f0ca1523
UUID=524079c6:521ca76f:126164a9:3232e116

Looks like the mdadm.conf is stale and should be recreated, and
recreate the initramfs. Thing is, the rd.md.uuid ought to be enough
for dracut to startup that array, the mdadm.conf is really just about
assigning a particular md array to a particular /dev/mdX assignment,
which by the way has changed recently so there might be confusion
going on there.

You might just try renaming the current mdadm.conf, or commenting out
all of the lines, except for one:

ARRAY /dev/md0 UUID=5a1848ce:cff64c1f:a622dc1f:e5f06d55

And after saving it, use dracut -f.

​I am having TONS of problems with f22 (af​
 
​ter reinstalling it
from DVD media, due to system corruption).
FOr example, after using dnf to install all the
mate packages that were previously installed (I had saved
the names of those packages in a different drive).
I had no desktop control. Mouse and KB did not work.
The one app that automatically came up (due to
settings of the mate env) was firefox , and for some
reason KB within the FF window worked, but nowhere else.
​yara ... yara ...yara..

When it rains problems, it pours :)
