I installed the Debian Wheezy ARMHF v1.0beta image from the UDOO webstie onto a microSD and put it in a UDOO Quad. I hooked up wired ethernet and the debug serial console to an adjacent windows machine. Upon boot I saw some errors with the audio. I performed sudo apt-get update, sudo apt-get upgrade and the boot error went away. I logged-in and then let everything sit for awhile (doing nothing with the debug console, wired ethernet, headless). (I'll want to use vnctightserver in the future so I can remotely access descktop on UDOO) After about 5 hrs I got the following kernel panic: Code: [20003.946289] Unable to handle kernel paging

e12fff1e e590317c (e5130004) Trying to debug this. Doe anyone know where I can find the system.map file for this build? NOTE: I was getting a similar kernel panic under Linaro Ubuntu 12.04 LTS. Thanks,
Re: Debian w/lxde Kernel oops - panic So, no system.map to be found. The two lines with: Code: Modules linked in: vivante drm Seems to indicate the problem is with the GPU driver? Perhaps the headless configuration is resulting in this failure... I need to either somehow disable the driver, or hook-up a display and retest ...
Re: Debian w/lxde Kernel oops - panic Update: I downloaded the Ardunio HFP IDE, but received an error with a lib when trying to upload I changed my sources.list to testing (jessie) and went through a twice interupted apt-get dist-upgrade (had two kernel panics in the middle of the upgrade). It was painful and I probably have a corrupt installation, but I recovered both times and was able to finally get it up and running. Jessie seems to run better (right now) and the Ardunio HFP IDE upload error went away (my servos are spining around right now). Refering to the post by jas-mx and the unofficlal debian jessie, it looks like jessie works better. Caution: its debian teasting which means things may break in the future. I'll cook this for awhile and report back if I get the same Vivante DRM kernel panic ... Meanwhile, I may try to build jas-mx's version and install it on my microSD
Re: Debian w/lxde Kernel oops - panic Kernel Panic after 4 hrs. Looks similar to prior kernel panics: PREMPT SMP...., except module is blank . Since this fs was an upgraded debian dist that was interupted twice I will not post the debug console contents. FRUSTRATING!
Re: Debian w/lxde Kernel oops - panic I have burned the Jessie image from jas-mx onto a SD micro debian-jessie-rootfs-with-gpu-vpu-t693.html#p5127 This seems to work much better and I haven't seen any kernel panics for 2 days now. I also had tried the Ubuntu 12.04 LTS ver 2.1 from the download page: udoo_quad_ubuntu1204_v2.1.zip. I didn't have any kernel panics with it either. I will mark this solved as with these new images the kernel panic problems are gone.
