Hello, Recently I tried F21 on that board. The result was a bit disappointing...
Apperently Fedora has several issues with that hardware: - thermal shutdown, after message something like "kernel trap/thermal zone/core0" - wlcore module error - some other error, possibly related to swap module /Need to redo testing here, not captured on logs/
What do You think? What is advisable to do /if any/ in this situation? I have some time, maybe can provide ssh/vnc access, if somebody is interested to examine issues. However, in that case we probably have to do something with that termal shutdown. I'm not experienced with specific kernel things that maybe involved.
Best regards!

I'm running F-21 on two revisions of the Panda-ES without issues. I'm running one with a minimal install and one with XFCE.
I've not seen any errors around thermal errors even when compiling things. Have you tried installing the kernel-tools package and running the tmon util? My devices sit at around 30 degrees at idle.
The wlcore module error is a known issue. I black list them as I don't use wireless. The chip needs a userspace util called uim to put the chip into the right mode, also the patches to support DeviceTree haven't landed upstream. In general the WiLink wireless drivers aren't in a great state.
I create a file called: /etc/modprobe.d/blacklist-wlcore.conf And add the following two lines: blacklist wl12xx blacklist wlcore
I can't help with the other error without more information. Overall with F-21 GA the Panda-ES does work relatively well in my experience. There's certainly some improvements to be made but it's generally very usable with XFCE or as a minimal install system.

Thank You fo reply, Peter!
I'have installed kernel-tools and banned wlcore. Than reboot before make new logs. Tmon indicates ~50C at Idle and goes 79 with little load. Based on previous expiriance it can't survive full system update, without termal shutdown.
Here is my logs: http://pastebin.com/L118YkDt http://pastebin.com/pfSLR2Fe http://pastebin.com/NH4G5egN
Last time I forgot to mention that mouse is working badly, but think that this is not important now. I use XFCE edition of F21. Power adapter is 2250 mA and I think that is OK also.

Any clues in top or cat /proc/interrupts?

It's be nice if there was some interrupt going nuts we could see in /proc/interrupts making execessive latency.
How about the U-Boot / MLO pieces? They have nasty deps like gpu clock state and default GPIO state.
If the only clue is excess heat it can be something like a contended SoC GPIO.

I think about that. I belive it is not related to interrupts or overload, because the system responce is very good. Also htop reported just a few percent load on both cores. Which is OK for XFCE, browser and several Terminals. I will make new logs soon.

I will also try detach any external hardware, once activate ssh.

I didn't understand U-Boot and MLO yet. But loader/configuration is stock Fedora one. It happen on two clean F21 installations on different flash cards. Before Fedora I tested Arch Linux Arm. Could that changed some firmware configuration? Is it a way to reset?

I doubt that too. I didn't used GPIO's and board is as clean as new. Unless it is defective.
My guess for now is that software somehow toggle wrong voltage/frequency. Is it a way to directly check that?
Maybe I will test with some old software that panda advertises, to see what will happen than. But don't know when, because it can take some more time.
Hi again, I make some more experiments to see what is going on.
The problem with mouse seems to be related with that specific model. When using other mouse it work perfect. Then I test with no ethernet, keyboard and mouse. The problem with overheating still persist. Processor load seem to be low and normal. Last I noticed that eth0 mac address changes between restart. Is there a way to make it permanent?

Sorry for the late response on this one.
My Panda-ES sits at idle around 20C using tmon so the temp is kind of strange. The Logitech Razor mouse is much higher precision so will generate a lot more data. If it's still a problem you might want to look at getting a heat sink to stick on the SoC.
BTW I'll have a fixed kernel for 3.18+ issues shortly.
