Hello Nicolas,

I think this was a know problem with older LXRT versions
and Pierre fixed it in CVS. But i do not understand how
you want to use LXRT to access your driver. LXRT hardrealtime
mode can not use Linux system calls, so a normal linux driver is
of no use. (i don't have your other post, so i don't really rember what
you wanted to do)
