Description of problem:
When running the kernel-2.4.21-15.ELsmp kernel on a Dell PowerEdge
4600, the gigabit tg3 interface drops about 5-7% of packets. I ran a
ping -f from two machines connected via CAT5 crossover to verify.
When using the 9.0.3 release of the 2.4.21 kernel, there are no
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run kernel-2.4.21-15.ELsmp
2. ping -f <machine over eth1>
3. See 5-7% dropped packets
Actual Results: 5-7% dropped packets
Expected Results: 0% dropped packets
Do you see error such as:
Jun 3 11:00:20 os-db01 kernel: tg3: eth0: Link is down.
Jun 3 11:00:22 os-db01 kernel: tg3: eth0: Link is up at 1000 Mbps,
In the output of dmesg? Are you running Oracle on this machine while
doing your tests? If so, it could be a duplicate of bug #123695
Yes, in dmesg,/var/log/messages -- and no, we are not running Oracle,
only Apache, MySQL, and Postgres. I believe the newest kernel update
has resolved this problem, as on one of the machines, I am not
noticing any more dropped packets.
