Is this still a problem w/ current FC5 kernels? If so, please try the FC5.netdev kernels: http://people.redhat.com/linville/kernels/fedora-netdev/ Does the issue still occur with the FC5.netdev kernels? Yes, it is. I've been using 2.6.16-1.2069_FC4.netdev.13smp for a while, and while the machine acts normally at boot, the problem shows up again after some time has passed, usually a week or two, sometimes a few days. Once it does start up, a soft reboot is not sufficient -- the machine needs to be power-cycled. I am currently installing 2.6.16-1.2122.2.3_FC5.netdev.3 (smp), and will report if I experience any more problem.s Optimistically presuming that the lack of further complaint indicates improvement of the situation... :-) |
Description of problem: Terrible network performance on tulip-based network card. Can't get above about 30k/s transfers on an unloaded 100Mbit LAN. Version-Release number of selected component (if applicable): 2.6.15-1.2054_FC5smp Substituting kernel 2.6.15-1.1833_FC4smp solves the problem.
