Hi,

I'm testing Qt 5.2.1 on a Wandboard using Yocto. If I build Qt5 without
udev support,
I get 3 or 4 of these kernel warnings when I start my application:

    idr_remove called for id=xxx which is not allocated.
    CPU: 0 PID: 538 Comm: xxx Not tainted xxx
    [<80013c7c>] (unwind_backtrace+0x0/0xec) from [<80011634>]

    [<800d9168>] (SyS_ioctl+0x38/0x60) from [<8000e180>]

Could anyone shed some light on the matter ?

My apologies if this is not the correct ml to ask this question.
