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_commo
0 [#1] PREEMPT SMP ARM" Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hello, I hope someone can have a hint on the following. I use xenomai 2.6.3 patched with kernel 3.8.0 on zynq. I wrote rtdm driver which coomunicated with fpga: the driver listens to irq line, and print something on each time it recieve an interrupt. If I do the rtdm_request_irq already at module init, I see that interrupt are given and there is no issue. But on trying to do the rtdm_irq_request from userspace application on ioctl, then I recive https://github.com/raspberrypi/linux/issues/32 oops. Another thing I see is that even when the rtdm_request_irq is done on driver init (not in ioctl), and in ioctl I just do simple printk then it will also get the oops : it is as if the irq interrups in rtdm driver interfere somehow with the ioctl call from userspace). I tried to debug this, but I have no clue so far. This is http://xenomai.org/pipermail/xenomai/2016-May/036338.html the Oops I get: zynq> zynq> zynq> cd /usr/xenomai/bin/ zynq> ./rtdm Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP ARM Modules linked in: xeno_rtdmtest CPU: 0 Not tainted (3.8.0-xilinx #17) PC is at 0xc0e8fae8 LR is at xnintr_irq_handler+0x118/0x3e0 pc : [
