    static int arcmsr_iop_ioctlcmd(PACB pACB, int ioctl_cmd, void *arg)
    uint8_t tmpQbuffer[1032];
    uint8_t tmpuserbuffer[1032];

    1kB allocations from the stack aren't a good idea considering that you
    might have only a 4kB stack altogether.

    Running "make checkstack" after compiling the kernel helps you finding
    such problems.
