Description Glen 2004-04-22 22:45:40 UTC

Description of problem:
So I've just upgraded a number of our machines from Red Hat 7.3 to
Fedora Core 1.  I've noticed that a number of them are having trouble
with their network cards now.  If I try and do anything network
related then the machines will just hang or time out.  If I look at
the output of the dmesg command I see errors like so:

eth0: ns83820_tx_watch: 0 3 3
eth0: tx_timeout: tx_done_idx=0 free_idx=3 cmdsts=2800002a
eth0: after: tx_done_idx=3 free_idx=3 cmdsts=00000000
eth0: ns83820_tx_watch: 3 4 1
eth0: tx_timeout: tx_done_idx=3 free_idx=4 cmdsts=0800002a
eth0: after: tx_done_idx=4 free_idx=4 cmdsts=00000000
eth0: ns83820_tx_watch: 4 7 3
eth0: tx_timeout: tx_done_idx=4 free_idx=7 cmdsts=0800002a
eth0: after: tx_done_idx=7 free_idx=7 cmdsts=00000000

If I shut down the network service, unload the ns83820 module, and
then restart the network service it usually fixes the problem.  None
of this ever happened on Red Hat 7.3.


Version-Release number of selected component (if applicable):
kernel-smp-2.4.22-1.2179.nptl


How reproducible:
Happens half the time after I boot the machines.


Steps to Reproduce:
1.  Boot a machine.
2.
3.
  
Actual results:
Sometimes the network won't work and I'll see those errors in the
output of dmesg.


Expected results:
I expect things to work fine like they did under Red Hat 7.3


Additional info:
The network cards in question are Netgear GA311 Gigabit PCI cards.

I've just noticed that this will happen ocassionally long after the
machine has booted and/or I've fixed things by unloading and loading
the module again.

Comment 2 Glen 2004-05-07 21:32:03 UTC

My boss said he found a solution: turn off kudzu at boot time. 
However, I haven't tested this theory yet.

I've got an SMC9452TX card that IDs as a National Semiconductor 83820.
This error cropped up during the install of Fedora Core 2, so I had to
fall back to the onboard NIC. Post install, same problem remains.
Update to 2.6.6-1.435 -- problem remains. Shut down networking,
removed the ns83820 module, started up networking, problem remains;
NIC can't even pull a DHCP address. Shut down networking, removed the
module, manually inserted the module, started up networking, problem
remains.

Other facts: athlon 1800XP system, nforce2 motherboard, nforce
ethernet NIC works great....

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
