I just finish installation and give it a try on reception: same problems 
than related by William. Seems that around 20 first kb of data's are 
approximatively ok and the garbage start (unexpected line lengths)

I use an X100P. SMP (2 celeron 400) 440 Mb RAM, with RH73 kernel 2.4.26, 
libtiff 3.5.7. So could be an SMP issue ...
