I just receive a message nve0: device timeout(n) with n any positive number (5..11 so far). With options MAXMEM=4194303 in my kernel config file the nve driver works mostly. Yesterday I was able to transfer ~500MB without any error. Then suddenly network traffic stops after nve0: device timeout(-1) Only solution was a reboot (I may try compiling the nve driver as a module and see if unloading/reloading of the module also helps). Today I'm getting tons of messages nve0: device timeout(4) (68 of these messages for ~260MB traffic) but after 2 seconds the link works again. Daniel
