I now have to reboot the guest to get igb1 back to a working state, then the link_irq will show "4" again, but I can't tell you what was first, the timeour-reset or the "link_irq" jam. I guess the latter can't be the case, but I have no idea about the code=85 Thanks -Harry --------------enigA6D2712F92354F24355F32F5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAlTnM/oACgkQLDqVQ9VXb8gxYACfaIWOMi+x15dJew4Xec3nRU5k 4/8AoMidWB9EewqQpElLnLsxxmlWL+e9 =duXv -----END PGP SIGNATURE----- --------------enigA6D2712F92354F24355F32F5--
