So this is hardware related. The hardware is in a big lab with AC and a lot of other servers and electronic cards so the EM must be quite big there.
I think everything is fine for me now. Thanks a lot for your time and help. I will update with url for RHEL4 and RHEL5 packages as soon as it is accepted by Fedora/EPEL people :) Antoine -----Message d'origine----- De : Charles Lepple [mailto:[email protected]] Envoyé : mercredi 12 août 2009 13:31 À : Antoine Gatineau Cc : nut-upsuser List Objet : Re: [Nut-upsuser] Usbhip-ups going wild On Aug 11, 2009, at 4:37 AM, Antoine Gatineau wrote: > On the machine connected to a MGE Evolutipn 1250, I got this message > during the night : > Aug 10 23:44:17 localhost kernel: hub 3-0:1.0: port 2 disabled by hub > (EMI?), re-enabling... > Aug 10 23:44:17 localhost kernel: usb 3-2: USB disconnect, address 14 > Aug 10 23:44:26 localhost kernel: usb 3-2: new low speed USB device > using address 16 > > It doesn't really bother me because it is reconnected in 10 seconds > but isn't there some issue here? > It is the kernel that disconnects the device but I wonder why... The kernel is disconnecting it, but that is based on a signal from the root hub hardware (probably on your motherboard). The EMI is likely caused by insufficient isolation between the USB hardware and the power switching circuitry in the UPS. _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
