"failed to add service - already in use?" since kernel Update >= 4.8.y



  • Hi guys,

    I am working on a RPI CM module with a builroot busybox linux.

    So my problem is that since i updated the kernel to Version 4.8.y i can´t run any qt apps anymore. Always getting:

    failed to add service - already in use?
    

    I tried all kernel versions up to 4.12.y. No one works.
    4.7.y and beneath are working .
    I am using the kernel source from there:
    https://github.com/raspberrypi/linux/tree/rpi-4.8.y/arch/arm

    Does anyone else has the same problem with qt and these kernel versions?

    I read that could be cause of the RAM/GPU spliting. But i tried a lot of different settings and no one works.

    These is my cmdline.txt:

    dwc_otg.lpm_enable=0 oops=panic panic=-1 console=tty3 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait logo.nologo loglevel=1
    

    and my config.txt:

    kernel=zImage
    disable_splash=1
    framebuffer_width=800
    framebuffer_height=480
    framebuffer_depth=24
    hdmi_force_hotplug=1
    hdmi_group=2
    hdmi_mode=1
    hdmi_mode=87
    hdmi_cvt=800 480 60 6 0 0 0
    max_usb_current=1
    config_hdmi_boost=7
    
    device_tree=bcm2708-rpi-cm.dtb
    device_tree_address=0x100
    kernel_address=0x8000
    disable_commandline_tags=1
    
    dtparam=spi=on
    
    dtparam=i2c0=on
    dtparam=watchdog=on
    dtparam=i2c_arm=on
    dtparam=i2c0_baudrate=400000
    dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=4
    
    

    If anyone had the same problem and allready fixed it or has some hints how to find out what´s going on here I would be very thanksfull.

    greets
