well, you top posted first, so I'm just going to reply in outlook :-) I think you have (for whatever reason) ASPM still enabled. If you send us (and look yourself) lspci -vvv then you may see ASPM: L0s and/or L1 enabled make sure to look in the LinkCtl: section
The only other thing maybe to check is the bits in the eeprom are updated to whatever we settled on as the latest. If you send the output of ethtool -e ethX we can check to make sure everything is okay. do you have the ASPM option on in your .config? -----Original Message----- From: Nils Faerber [mailto:[email protected]] Sent: Monday, August 09, 2010 3:19 AM To: [email protected] Subject: Re: [E1000-devel] e1000e latency issues As addendum here is a short ping log: 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4093 ttl=64 time=0.581 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4094 ttl=64 time=18.2 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4095 ttl=64 time=186 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4096 ttl=64 time=0.565 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4097 ttl=64 time=542 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4098 ttl=64 time=0.870 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4099 ttl=64 time=792 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4100 ttl=64 time=1.52 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4101 ttl=64 time=188 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4102 ttl=64 time=1.11 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4103 ttl=64 time=648 ms 64 bytes from piwi.kc.de (192.168.2.28): icmp_seq=4104 ttl=64 time=112 ms As you can see every second ping (at least every third) has times >> 100ms, in this log up to 648ms but they can even exceed 1000ms. I really need that interface to behave so any help would really be appreciated...
