This sounds like a bug in the tg3 driver in that kernel version. Have you checked the RedHat bugzilla to see if anyone else sees this? Depending on how the motherboard is laid out, moving the UPS to a different USB port might avoid this problem. It could have something to do with interrupt handling (for example, the tg3 driver expects an interrupt that is stolen by the USB controller). -- - Charles Lepple _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
