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
