I'm still testing with MSI enabled. So far tried rebooting using nextboot(8) (just in case i lost the network card i could boot again) and the card seems to work but i'll continue stress testing the machine with stress + dd + iperf and see if i can take it down. I'll let you know how it goes. Regards. -- La prueba más fehaciente de que existe vida inteligente en otros planetas, es que no han intentado contactar con nosotros.
