I'm using the 192Mb configuration. I compiled the kernel on ubuntu 12.04. Here is the kernel.img i'm booting on: http://dl.dropbox.com/u/22600720/rpi/kernel.img and the .config file I used: http://dl.dropbox.com/u/22600720/rpi/.config Compared to the default .config i have added I2C and pvrusb2 and such drivers. I'm plugging a Hauppage HVR-1900 on the pi for TV recording. The problem occured after about 1h 10 minutes of recording from the device. Concretely it means streaming ~1Mb/s from the USB to the SD card. The CPU is relatively OK when doing that, like at 15%. Because I have seen frame drops doing that, I am using two processes for the recording, one of which runs at realtime scheduling priority, using that flywheel program described there: http://www.isely.net/pipermail/pvrusb2/2011-March/003037.html So after about 1h I get that kernel error. I have had that same problem several times now, the previous time with the same kernel but the original firmware that came with the debian image, but then I didn't get a log in the kern.log, unlike this time. and here is the full stack trace: Jun 3 16:24:22 raspberrypi kernel: Internal error: Oops - undefined instruction: 0 [#1] PREEMPT Jun 3 16:24:22 raspberrypi kernel: Modules linked in: ipv6 fuse tda10048 tda18271 tda8290 tuner cx25840 pvrusb2 dvb_core cx2341x tveeprom v4l2_common videodev i2c_core Jun 3 16:24:22 raspberrypi kernel: CPU: 0 Not tainted (3.1.9 #2) Jun 3 16:24:22 raspberrypi kernel: pc : [] lr : [] psr: 60000013 Jun 3 16:24:22 raspberrypi kernel: sp : c8893ea0 ip : 00000000 fp : c8893ecc Jun 3 16:24:22 raspberrypi kernel: r10: c0388594 r9 : 00000000 r8 : 00000001 Jun 3 16:24:22 raspberrypi kernel: r7 : 00000000 r6 : 00000001 r5 : 00000010 r4 : c

It means that the compiler converted your code to an instruction that the hardware does not support. This could however be something simple like disabled floating point operations. see infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0363g/… –Guru Prasad Mar 26 '15 at 17:27 add a comment| active oldest votes Know someone who can answer?
