Well, I think so, because everything else works. Mplayer is especially peaky about the compiler, isn't it? And it works. Everything works, but when I quit X server, the kernel crashes :-( NIP points to 000003B4?? Overwritten?? LR points to 0xc002b540 -- 0xc002b478 + 0x00c8 do_generic_file_write SP seems good. Still trying to locate it. BR, Matej
