Hi, I sat down to do some testing of the ixgb driver a few days ago, and get failures within seconds. From what I can tell, I'm getting either a DMA to a bad address or some other PCI bus error, not sure which. The problem appears to happen only for the driver that's in 2.6.17-rc6-mm2. As a sanity check, I'm testing the SuSE SLES10 beta, which is 2.6.16 based, and it doesn't seem to have any problems.
My test is dirt-simple: telnet to the chargen port. After an eyeblink, I get the pci bus error, that's that. "eyeblink" is after about 300MBytes transfered. That was with a driver with NAPI enabled. I tried again with NAPI disabled, and got to about 1.8 GB transfered in two eyeblinks. To make sure that I'm not dealing with faulty hardware, I tried the same thing w/ SLES10 2.6.16.18-1.8 and have gotten to RX bytes:20889480686 (19921.7 Mb) so far, with no problems. I don't have easy access to a PCI bus analyzer, otherwise, I'd tell you more. Ideas? Suggestions? I could try taking the diff between these two driver versions, and seeing what change caused the problem, but thought I should email first, before doing that. --linas - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
