Description phil 2007-01-31 15:42:03 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0

Description of problem:
periodically my 2nd NIC (a natsemi ethernet card) locks up - a "service network restart" is needed to get it going again.

just before this happens, the following message appears in /var/log/messages

eth1: Oversized(?) Ethernet frame spanned multiple buffers, entry 0x3df74a status 0xd00005f2.

i have a busy server where this happens once or twice a day.

my eth1 reports as following in dmesg

natsemi eth1: NatSemi DP8381[56] at 0xddedf000 (0000:03:0d.0), 00:09:5b:e1:8c:97, IRQ 225, port TP.




Version-Release number of selected component (if applicable):
kernel-2.6.9-42.0.8

How reproducible:
Always


Steps to Reproduce:
1. switch server on
2. wait until 'Oversized(?) Ethernet frame spanned multiple buffers' appears in /var/log/messages
3. observe fault

Actual Results:
the ethernet controller will have locked up, making my web site unavailable

Expected Results:
nothing

Additional info:
i am concerned that this is a bug in the natsemi ethernet driver, having found the following on the web. can someone perhaps check this fix did actually make it into the current rhel4 kernel???


Natsemi oversized packet lockup
Friday, February 10th, 2006

If you're having trouble with a natsemi ethernet controller locked up in Linux after complaining about oversized ethernet frames like this:

Oversized(?) Ethernet frame spanned multiple buffers, entry 0x00ba8b status 0xe0000bd5.

then this patch (or a kernel version which includes it; 2.6.16 or later should) may be useful. The patch is against 2.6.9+ versions of natsemi with NAPI support but doesn't use the NAPI support.

Comment 1 Andy Gospodarek 2007-01-31 23:19:42 EST
That patch is not currently included in RHEL4.  I will probably build a RHEL4
test kernel that includes that patch in the next couple of days and will post
here when complete.  

Will you be able to install it and test it on your system reasonably soon?
Comment 2 phil 2007-02-01 02:39:48 EST
Andy-

Yes, I should be able to try this out!

Comment 3 Andy Gospodarek 2007-02-01 17:04:08 EST
Test kernels are available here:

http://people.redhat.com/agospoda/#rhel4

Please test them and report back to this BZ.
Comment 4 phil 2007-02-02 06:24:57 EST
OK I have installed 2.6.9-45.EL.gtest.9smp this morning - currently running
without problems.

Comment 6 Andy Gospodarek 2007-02-06 10:25:05 EST
Phil,

Please let me know if you see these hangs with the new kernel.  If not I will
try and push this patch into a future release.  

Thanks for sending it to us.

No problems so far - the server has been running fine since 2007-02-02 06:24
EST, so I'm pretty sure this is an improvement.
