Created attachment 540252 [details]
screenshot of said situation

Description of problem:
kernel does not activate /dev/md1, does not see pv and thus no lv's to boot the system

Version-Release number of selected component (if applicable):
kernel-3.1.2-1.fc16.x86_64

How reproducible:
upgrade to f16, install kernel, boot kernel

Steps to Reproduce:
1.
2.
3.
  
Actual results:
dracut prompt

Expected results:
system running

Additional info:
at the dracut prompt I can assemble /dev/md1 by hand

also:

kernel.org kernels compiled since upgrading to F16 have failed boots: monitor goes into powersave as soon as dracut starts; no network after a while, no /var/log/messages 
own 3.0.3 rt kernel does boot fine though, so raid and lvm are ok.

So kernel.org kernels you've built also fail in the same manner?  If so, this might be some kind of issue with dracut, udev, or device-mapper.

Which upstream kernels have you tried building?

I cannot actually verify what happens with my own kernels due to the monitor going into powersave and no network etc.
If you have a trick to turn the monitor on from powersave I could give that a try.

I tried 3.0.9 and 3.1.4 kernel.org kernels.
Both without rt patch and 3.0.9 with rt patch.
I diffed the 3.0.9 rt config with the working 3.0.3. rt config and there's no real differences there.

kernel 2.6.41 from F15 also does not activate /dev/md1.


changing the name of /usr/sbin/vbetool does not change the pwoersave behaviour of the kernel.org kernels built under F16.

How can I check what goes on when the screen goes into powersave?

modprobe fbcon was a step towards a solution
