[fedora-arm] Possible Hangups on Raspberry Pi with FC25 Server

Discussion:

Hello,

I recently bought a Raspberry Pi and I want to use it as a small server. I installed FC25 on it. The only additional piece of hardware is a bluetooth keyboard/mouse device, which is connected via usb dongle. On the software side I only installed a samba server and opened the related ports with a firewall command.
This installation is working and I can access the shared folder. However after a while - it differs - the server isn't available anymore. No ping is possible, also there is no HDMI signal anymore - the only thing I can do is restart it. I'm keeping the software up to date, but that doesn't solve the problem.
So what I would like to ask is, if there are known stability issues? Or is there something I can check and maybe fix? Maybe I could provide some details (not sure what - log doesn't tell anything usefull) to track down any issue.

Best Regards
Alex

Hi Alex,

quite a while ago I had a similar problem which turned out to be a
hardware issue. First thing you should check is the power supply.
Furthermore you could check if you have any missplaced heatsink nearby
any metal pieces. Also a metal case could probably cause problems.

Regards,
Daniel

There's no known issues I've seen running it from a Server PoV but
there's some common issues. Do you have the storage for the share on a
USB HDD or is it just sharing space on the SD card? What model of RPi
is it and what is the amp rating on the power supply. The most common
issue is caused by a PSU that's not strong enough.

I had exactly the same issue some time ago. The strange thing was that
all USB related devices (keyboard, network card) and HDMI was not
working, but the system was still somehow alive and I was able to
find valid records in logs about the system activities. When I
equipped the RPi with more powerful PSU (5V/3A) the issue disappeared.
My conclusion is that even the RPi do not need to consume much in
average, there are some peaks when it need a lot of current. If a PSU
can not provide the required current, it survives, but USB bridge dies
(it means also NIC).

Regards,
Jan

Yes, USB is a big power draw as is any wireless interface. To date 90%
of stability problems with the RPi that I've seen have been due to not
having a PSU with enough guts.

Hi,
the Pi is a 3 Model B. The output of the PSU says 5.1V and 2.5A. Is that
enough? Also I don't have any further storage connected. For sharing I'm
using some space of the 15G card where the OS is installed on.

Hi all,

Since a couple of days I'm hit by hangups as well :( Hard to trace
since the Raspberry Pi 3 does nit react to keyboard, network etc.
anymore and the HDMI monitor goes black.... However, yesterday I was
able to take a photo before the screen goes black: Kernel Panic ...
Fatal exception in interrupt; screen shot attached!

This raspberry Pi has been running for weeks without problems on Fedora
25 using the same power.

Hmmm, any sugestions on this?

Hi all,

since I wasnÂŽt able to find out whatÂŽs causing those crashes I moved to
raspian and since then the Pi (it was a Gen 3, Model B) is running without
any hickups. So in the end IÂŽm sure, the issue was software related.

Yes little surprise there, unless it's PSU and we're not as power
optimised as Raspbian yet.

In terms of software, other than the fact they're both Linux distros,
that link Raspbian and Fedora 25. Kernel, toolchain, their binary
display drivers etc are all different. We're all upstream and open,
it's not yet perfect but it's all open but we're not yet the most
power efficient.

Fedora might not be perfect if your doing client stuff and need display drivers. However it is really great if you need a small server, because it is the only maintained distro for the Raspian shipping SELinux by default! Thanks for anything your doing Peter ;)
