<-- snip -->

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.
