I can confirm this bug on Ubuntu LTS 6.06 LTS using any of the 2.6.15-x series kernels.
Upon booting I would get the exact same message as the previous poster. /sbin/ifconfig eth0 reports "Device not found" The bug is not present in the Ubuntu Hoary or Ubuntu Breezy distributions because they use older kernels. I think this problem may be an upstream problem, perhaps due to http://bugzilla.kernel.org/show_bug.cgi?id=5507, because Ive compiled a 2.6.18-rc1 series MM kernel and that doesn't exhibit the same problem. -- kubuntu 6.06 LTS does not support Realtek 8139 network card https://launchpad.net/bugs/48456 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
