Well, WTF ! An in depth study can found here. According to Randy Kramer "Turns out that there is a bug in ping which causes me to see the "wrong data byte #0 should be" 0x59 (0xhh?) "but was" error message, if the ping response takes longer than 1 second. Thanks to Pierre Fortin for pointing this out(...)"
