After excluding some possible reasons, like bad cables, other machines on the net, a beserk hub, I suddenly remembered I had booted a new kernel some time before I noticed the problems. And the cause for my problems was this option in my kernel config: options "NMBCLUSTERS=1024" All I did to fix the problem was remove this option, and build a new kernel. No more input errors ! What seemed to be a hardware problem turned out to be 100 % software. Just so noone else stumbles into this :-) Cheers, Michael
