Finally my connectivity problems turned out to be caused by four blown up 470uF/25V capacitors by the infamous STONE-Company on the board of the Linksys SD2005. You might want to google for "stone badcap" and "linksys sd2005 bad caps" to get the whole story.
It took me quite a while to prove that by replacing the switch with a known good one. Sorry for not checking that first, but the symptoms were just like the ones in this bug report and the driver README was too comfortable to follow. -- Intel Gibabit Ethernet NIC (82541PI) operating at 100Mbps instead of 1000Mbps after upgrading to Hardy https://bugs.launchpad.net/bugs/309211 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
