AMD Ryzen 7 freeze on YouTube
by Lukas Zapletal
Hey,
I encountered weird Ryzen 7 freeze when playing youtube video, it kinda stuck in a few seconds loop, the computer was unusable and had to hard reset. While I will be trying to pull out something useful from logs next time (I don't have persistent journal set), anyone experienced the same? This is up-to-date Fedora 25, I was using Google Chrome stable.
Is this something to do with Ryzen bug FMA3? How do I check? I do have latest BIOS update, but unsure how to check this bug. Is there a test? I also have older GeForce card, using open source drivers.
Thanks for any hints which direction I should dig. Thanks.

post-mortem: f24 boot fails; need help.
by William
Good morning,
The "f24 boot fails; need help" problem set me back a week. I'm still
catching up. I seriously believe it would be foolish for me to just
forget it. I should for the benefit of others try to get at the real
cause and possible prevention.
A few hours before the failure, I received and looked at an e-mail that
I'm almost certain was at least a spoof, and possibly malicious. I know
it contained html and links. I did *** not ***
click any of the links. I looked at it, and deleted it. It was viewed
in Thunderbird only. The message's "From" ended with "yahoo.com". My
question: It is highly improbable that that message had anything to do
with the boot failure. Am I correct?
Also a few hours before the failure, I did some web browsing using
Firefox with NoScript and uBlock Origin. As best as I recall, the
"riskiest" sites that I visited were finance.yahoo.com (and a few of its
sub-pages, I clicked no ads, no ad links) and indeed.com (possibly and a
posting or two). My question: It is highly improbable that my web
browsing had anything to do with the boot failure. Am I correct?
thanks,
Bill.

Control audio output between Line Out and Headphones
by Daniel Krebs
Hi,
I'm struggling to configure the audio output of my Fedora 25
installation. I'd like to find a way to easily switch between front
audio (headphones) and line out in Gnome Shell without physically
plugging/unplugging any jacks.
So to clarify my setup is as followed (on ASUS PRIME B350-PLUS Mainboard
with Realtek ALC887 Audio Codec):
* Headphones connected to the front headphone jack of my case via
internal mainboard header
* Amplifier connected to green jack on the mainboards backpanel
When both, amp and headphones, are connected, the sound is only played
via headphones. In the Gnome audio settings the the line out output
device disappears and there is only the headphones output device.
Then I used alsamixer so change "Auto-Mute Mode" from [Enabled] to
[Disabled]. This way sound is played via amp and headphones
simultaneously. Gnome audio settings still shows only the headphones as
output device. I can than change Volume of "Headphones" and "Front" via
alsamixer separately to get any mute/unmute combination I want but
obviously this is neither comfortable nor compatible with any gnome
extensions that would let me change output easily (like
https://extensions.gnome.org/extension/906/sound-output-device-chooser/)
I generated more Information with the alsa-info.sh script which can be
found here:
http://www.alsa-project.org/db/?f=9c9fd41a57760353f5989f85ae5b8e9185d1c2f6
Any Ideas?
Thanks

Fedora Kernel 4.11.x problem
by Cristian Sava
I tried to upgrade my F25 to kernel-4.11.x and I can't boot with it.
I have two independent F25 installs, one on ssd and one on sda - boot
switched from bios menu. Both failed to boot 4.11.x
Immediately after selecting 4.11.x my system freezes without any
message (tried without rhgb, etc. with no luck)
The older 4.10.17 and 4.9.14 are ok. So not a grub problem.
My box:
Asrock Z77 Pro4 (legacy bios setting)
I3-2120
16GB RAM
Radeon 7700
Intel 535 ssd
Seagate and WD disks

IP address or DNS name (bug or feature)
by Walter H.
Hello,
as this is the first time I'm using Fedora, I noticed the following ...
(a) when open a SSH connection, it tells e.g.
Last login: Mon Jun 5 20:14:37 2017 from 192.168.1.1
all other Linux VMs and/or the Router box show there
Last login: Sat Jun 3 21:41:45 2017 from winpc.local
(b) when configuring Firefox using a proxy, this works only
when entering a IP address; when entering a DNS name
a 'Proxy server not found' error is the result ...
(c) when configuring a line printer I had to enter e.g. this
lpd://192.168.1.11/CP1515N
when entering a DNS name e.g. printer.local
then this result in a 'printer.local' could not be found;
a nslookup shows the correct IP addresses
this means the DNS server is working properly ...
Thanks for explanations,
Walter

The SMS data is in a protected directory on Android phones. I believe
the call logs are as well. Unless your phone is rooted, you won't have
access to them. There are utilities out there in Android-land that will
let you back up SMS data and call logs, or you can root your device.
>From what I can remember, the SMS data is in
/data/data/com.android.providers.telephony/databases/mmssms.db
on the phone. Unless you're rooted, /data reports as an empty directory.
Android is essentially saying "Nah, it isn't empty, but you ain't root
so you can't see what's here. So there! Nyah! Thhpt!" <insert emoji
with a thumbed nose here>
There are times I absolutely hate Android. It's my phone. I should be
able to do what I want with it. Why the hell can't I move stuff to and
from my SD card as I see fit? Truly annoying.

Not sure if that means I would be able to copy them to linux.

Update to libdb-5.3.28-21.fc25 in F25 will break the rpm database.
Repairable by rebuilding rpm database with rpm --rebuilddb
by stan
There is an update (or test update) of libdb for F25 that, when
installed, breaks the rpm database because it is incompatible. The dnf
update completes, and then hangs (at least it did on my system). The
fix is to remove the old rpm databases (this might be optional), and
rebuild the rpm databases.
rm /var/lib/rpm/__db.00? # optional?
rpm --rebuilddb
I did a reboot to sync everything that uses libdb (anything that uses
the Berkeley db). It might be possible just to restart affected
applications if that isn't an option. That worked for my mail client
before I rebooted.

postgresql and firewald startup
by Jeandet Alexis
Hello,
I have a server running F25 with postgresql and firewald configured.
On startup postgreslq always fail to start complaining about port 5432.
I did allow this port on the firewall, if I start manually postgresql
after it works.
So I did plot the startup sequence (systemd-analyse plot), I saw that
pgsql start after dbus.service but much before the firewall. Is there
something wrong with the default config of pgsql systemd unit?
Or more likely, what did I miss? mess :)?
