RE: [suse-amd64] Tyan S2881 network problem
Joe, What do you consider large files? I've got a 2 servers with MSI mother boards with the BCM5704 (don't know what the C difference is) chip and we nfs/sftp/rcp multi gig files. Nothing larger than 12 GB at this point though. We are quite pleased with their performance. This is both under SLES8SP3 and SLES9. -Alain -----Original Message----- From: Joe Georger [mailto:jgeorger@ll.mit.edu] Sent: Monday, June 13, 2005 12:17 PM To: Brad Dameron Cc: suse-amd64@suse.com Subject: Re: [suse-amd64] Tyan S2881 network problem We've got 7 of these units.

We have gone from Suse 9.1 Pro to 9.2 Pro to SLES9 and nothing is staying up. Is the BCM5704C really that bad? I can't blame the OS because I just can't believe SLES9 would lock up like that.

Actually the 2881 has been know to have Ethernet issues. I have had to return a few because the ethernet would stop working after pushing a few hundred MB over it. But they would work at first. The above message would indicate either a delay from spanning-tree turned on your switch, auto-detect on the port not working thus setting it to something like half-duplex and the BCM trying to communicate at full duplex, bad ethernet cable (Verify link lights are on), or bad ethernet.
Have you ran "ethtool eth0" to see if you have a link, etc? Can you get us that info? Also is it loading the BCM5700 driver or the TG3?

Our files are typically 2 GB each. I think Tyan is using the non-C variant on their newer, PCI-E/nforce Pro boards. In googling I have seen a post of two of people saying the BCM5704C dies under anything more than a moderate load. Joe Black, Alain wrote:

BCM5704C usually dies due to electrical issues (capacitance) rather than driver issues. Not such a popular IC as a result any longer. Seemed to be prevalent mainly when the CSA Gigabit bus was born and CSA Intel was quite expensive - Broadcom as a PCI bus device was more desirable, but at the same time quite problematic. -----Original Message----- From: Joe Georger [mailto:jgeorger@ll.mit.edu] Sent: 13 June 2005 21:44 To: Black, Alain Cc: Brad Dameron; suse-amd64@suse.com Subject: Re: [suse-amd64] Tyan S2881 network problem Our files are typically 2 GB each.

It is not the BC57xx chipset in general. It is the implementation of it on the Tyan S2881 early versions of the motherboard. They have since corrected it and you can get a replacement motherboard from them. Brad Dameron SeaTab Software www.seatab.com
My vendor (Colfax) got in touch with a senior engineer at Tyan. Here is an excerpt of what he said: There was an issue that affected some of the early production boards around the middle of 2004. This problem can only be duplicated in Linux under very heavy network traffic. The issue was fixed with ECN letter "D". It should be near the back corner on the board (near the second PCI-X slot). If it is before ECN "D" then a replacement is recommended. So thanks for the info Brad. I will be checking my boards and let the list know for sure that they are indeed the older, defective models.
