[Bug 279024] New: network breaks down with e100 driver on a core duo box under heavy network load
https://bugzilla.novell.com/show_bug.cgi?id=279024 Summary: network breaks down with e100 driver on a core duo box under heavy network load Product: openSUSE 10.2 Version: Final Platform: i686 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: admin@eregion.de QAContact: qa@suse.de I recently bought a HP pavillion s7749.de which has an intel gigabit interface onboard, and found that under heavy network load (like untarring a 17gb tar file from a nfs share) the network becomes unusable, with ping responses like these: celebrimbor:~ # ping nyuu PING nyuu.eregion.home (192.168.238.249) 56(84) bytes of data. 64 bytes from nyuu.eregion.home (192.168.238.249): icmp_seq=1 ttl=64 time=21.3 ms 64 bytes from nyuu.eregion.home (192.168.238.249): icmp_seq=4 ttl=64 time=10.5 ms --- nyuu.eregion.home ping statistics --- 32 packets transmitted, 2 received, 93% packet loss, time 31008ms rtt min/avg/max/mdev = 10.524/15.943/21.362/5.419 ms 93% packet loss on a local lan? not good. not at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=279024 ------- Comment #1 from admin@eregion.de 2007-05-31 09:21 MST ------- additional info: no matter what i do with ethtool, the performance feels like 10mbit halfduplex. but if i switch off autonegotiation, at least the link doesnt break down anymore, its just slow as molasses (copying from nfs to the box in question: 875kb/sec; copying from the same server to a different box: close to 10mbyte/sec). switching to a different port on the (brand new) ethernet switch didnt help, and performance on the box in question when running windows is ok, so i think it cant be the hardware itself. am going to try the latest linux driver from www.intel.com later tonight. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=279024 ------- Comment #2 from admin@eregion.de 2007-06-01 01:28 MST ------- more additional info: with the latest e100 driver from intel.com, built directly from the tar file into a rpm by using rpmbuild -ta, the network doesnt break down anymore, and gets a 100mbit fullduplex link without any ethtool options in the ifconfig file. BUT: the speed still is on 10mbit level. a bit better, 1mbyte/second instead of 850kbyte/second, but not what i'd expect on 100mbit. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
