Indeed, although I didn't think it _that_ unusual. It's just a 19" rack appliance with 2 expansion slots for 4x LAN ports each. And those are based around sky2. But we have had problems before with kernel 2.4.34/.36 as well with that hardware. They just weren't as easily reproducible but manifested themselves in occasional malfunctions of the network devices that could be solved by an ifdown/ifup cycle. We still have one spare box and will try that one in case the hardware is really flaky (which would be strange, given how reproducible it is right now). > Would you mind adding the phy_lock fix on top of the latest net-2.6 > git version of sky2 and testing that? Tried it, doesn't fix the issue. What would be the simplest change to stop disabling phy when the last device goes down? best regards, Rene -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkp5d6AACgkQq7SPDcPCS95OuACggTuTHsZd7m6IqHt0mrqUZbju G4wAoPfPGr5G05E6HdO9kcKflGaSx7f5 =78yk -----END PGP SIGNATURE-----
