Is that right? You might try uncommenting the "#define DEBUG_NE2000" line in hw/ne2000.c, recompiling, and then comparing the debug log from a vanilla guest kernel against the debug log from a suspend2 guest kernel. Good luck. -- john Simon Guerrero wrote: > I'm figuring that nobody has an answer for this.
