Description Michael 2004-05-21 19:28:18 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET 
CLR 1.0.3705; .NET CLR 1.1.4322)

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 
problems.

Version-Release number of selected component (if applicable):
kernel-2.4.21-15.EL

How reproducible:
Always

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

Comment 1 Bastien Nocera 2004-07-05 10:52:28 UTC
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,
full duplex.

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

Comment 2 Michael 2004-07-05 16:54:56 UTC
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.
