rtai 3.1 - I can't unload lxrt

[Dario Dallefrate]

Dear RTAI developers,

I'm using the latest cvs rtai 3.1 with kernel 2.4.27-adeos and after having 
loaded lxrt module I can't remove it.

When I try I get the following error:

Unable to handle kernel paging request at virtual address e09bf7e8
 printing eip:
e098818f
*pde = 015d6067
*pte = 00000000

Any suggestion?

Best regards
