powertop

[root at f25h ~]# ls -l /var/cache/powertop/

-rw-r--r--. 1 root root 0 Dec 29 14:49 saved_results.powertop
These files are always 0 length files. I'm not finding that any of the
calibration runs I've done are actually getting saved.
And each time I do a calibration...
[root at f25h ~]# powertop -c
modprobe cpufreq_stats failedLoaded 0 prior measurements
That suggests there are no measurements. So... is it broken on F25 or
am I missing something? I've asked on the powertop list and there's
been no reply.

F25 libvirtd complains unsupported config, can't find a VG

i'm seeing this in the journal.

I'm also seeing the VG, which is named 'vg' inactive in virt-manager >
Edit > Connection Details > Storage and it can't be made active, I get
an error:

However, if I use virsh edit and just specify path to any LV on this
VG, the VM works and uses it without complains.
Soo....it's active as far as LVM is concerned but libvirtd won't
"manipulate" this pool even though it'll use LV's in it, for reasons I
can't figure out.

lvm services enabled without any lvm devices
by François Patte
Bonjour,
I installed fedora 24 on 2 (software) RAID1 disks: in that case,
anaconda do not set any lvm but some lvm services are enabled and running:
lvm2-monitor.service
lvm2-lvmetad.socket
lvm2-lvmpolld.socket
Is there any reason for this and can I disable them?
I have some problems at shutdown with the raid devices (sometimes
shutdown hangs and I have to use the power button to turn the computer
off) and I am searching to have a minimum necessary services enabled.
Thank you.

firewalld broken dependencies on f24
by François Patte
Bonjour,
For this reason, it is impossible to change any settings in firewall on
fedora 24.
So, I can't ssh machines running f24, I can't set printers on machines
running f24...
Is there a solution?
Thank you.

Is there a way to specify that boot should be deterministic instead
of using threads?
by stan
Kernel booting used to be deterministic. That is, if you booted the
kernel 10 times, every one of them would be exactly the same. Then,
several years ago, the kernel boot process was made threaded to speed
it up. This means that every boot is slightly different.
Is there a way to make the kernel boot in deterministic fashion again?
Everything will be done sequentially, and no task will kick off if its
predecessors are not done.
Kernel boot parameter, dracut option, systemd option?
Thanks.

gcc warning and errors
by Patrick Dupre
Hello,
I have a Makefile (gcc) generating a lot of warnings. Hence, it is difficult
to see the error message.
How can I have the gcc error message in red?

issue wth nouveau driver on f25
by François Patte
Bonjour,
I just installed fedora 25 and I have a problem with X11: When a user
logins, the screen blinks several times (alternating console and black
screen) before displaying the graphical screen.
In Xorg.0.log I get this message (repeated at least 4 times for each
user login):
(EE) NOUVEAU: failed to set gamma: permission denied.
I had not this problem with fedora 24.
What's wrong?
Thank you.

firefox on fedora 25 unable to apply css rules?
by François Patte
Bonjour,
I just installed fedora 25 on my laptop. firefox 50 (or 49) is unable to
display fonts if I put this css instruction:
* {
font-family: Freeserif, Helvetica, sans-serif;
}
If I comment this in the css file, I can see the text if not: all
decorations, and images are displayed but no text appears!
I tried with google-chrome and the page is correctly rendered.
Thank ou for any clue!
