After upgrading to kernel-2.6.16-1.2107_FC5 on an x86 and an x86-64, network
stopped working. x86 got an IP address from DHCP server. But ssh/rlogin
doesn't work in and out. On x86-64, I couldn't get an IP address from DHCP
server. Downgrade to kernel-2.6.16-1.2096_FC5 fixes problems on both machines.
Appears to be the same problem as #190586
