DPMI_CallRMProc trouble

[György 'Nog' Jeney]

I realy need help with this.  Whenever I call a DOSDEV_ function then that
function eventually calls DOSDEV_DoReq.  This function calls DPMI_CallRMProc.
Now that function call DOSMEM_GetBlock( 64, (UINT16 *)&(context->SegSs) ) to
try and allocate a stack. This fails for some reason but I dont understand
why because it succeds if called from int21/48.  Anyone know whats going on?
