Hey guys,
I have bought Raspberry Pi 2 and just started working on it two weeks ago, and for me, it is just completely unstable.
First, I bought a Class10 microSD card because I needed a swift booting, I downloaded the latest Raspian version and wrote it on the SD card, and it worked fine.
I tried then to install some programs, I started with MJPG-streamer and it didn't work because of a conflict with the new kernel 3.18 but found a modified version of it that fixes this conflict. I also installed VNC server, Arduino and other programs; by then, problems started to appear. When I reboot or power up the raspberry, I can see the kernel messages on the screen and there was some repeated message repeats again and again, it didn't stop until I removed the keyboard ! After booting I plugged it again and it worked. Then, the webcam which I connect to it, also didn't make it boot, I had to remove it to let it boot. Actually, this wasn't the case in the beginning because I managed to boot the raspberry with these stuff plugged in, but something I don't know happened !!
Other times, when I don't connect the Raspberry to the screen, and just use SSH, the raspberry doesn't boot even if there is nothing at all connected to it; and I have to format the SD card, re-install the system, and sometimes even re-installing the system doesn't solve the problem and I have to FULL format the SD card to make that work !!
I got busy and forgot about it and just today started to work on it again. I started by installing the system again, everything worked great. I installed MJPG-streamer - the modified version - and everything worked awesome. I installed VNC server, everything was great - even when USB devices are connected to the raspberry and booting and rebooting is fine-. When I installed Arduino and rebooted, the raspberry didn't reboot. And I even cannot see anything on the screen !!
I re-FULL-formatted the SD card, installed the system, powered the raspberry up and it worked. I installed the Arduino alone - using sudo apt-get install arduino - and rebooted, it didn't reboot.
I cannot be 100% sure that this is the source of the problem because it is completely strange for me; because I had Raspberry Pi B+ and this never happened when installing Arduino - but this problem repeated many times.
I am sorry that I cannot provide the kernel messages because the problem happens when it is unable to boot so I cannot get the message (I usually unplug the power and re-plug it).
So anyone has any clue what this is ?!!
