ping delay network issue
I've bought a new intel dn2800mt mini-itx board with atom proc and intel e1000e onboard nic and installed slackware32 13.37 just like I did on 2 other PC's.
Any PC on my network I try to ping from the atom PC has strange delays in ping :
I have swapped network cables.
Both PCs connect to the same switch. I also tried a different switch.
I updated the e1000e driver on the atom PC from 1.2.7-k2 to 188.8.131.52.
I recompiled the kernel for Atom processor and included the e1000e driver in the kernel now.
Yesterday I booted with a Live CD "backtrack5 linux" Ubuntu based and then the ping problem is gone.
This leads me to believe that it must be some slackware/driver issue
What could this be?
Do you have linux-firmware installed? It provides a bunch of binary blobs for network cards and such.
I also noticed that the backtrack-linux cd has a newer kernel than I am running with on my stock 13.37 (184.108.40.206)
Maybe I should try to upgrade to slackware-current. I have always run with 'released' slackware versions without updating much inbetween major releases.
Yeah that kernel is pretty old. I'm running Arch and my kernel is version 3.4.9. Kernel updates usually help when it comes to drivers.
Linux riwiatom 3.2.29-smp #1 SMP Mon Sep 17 13:02:10 CDT 2012 i686 Intel(R) Atom(TM) CPU N2800 @ 1.86GHz GenuineIntel GNU/Linux
Unfortunately not a complete solution but I do see improvement.
No ping delay varies between 0.600 ms (mostly) to 5-15 ms occasionally
So not as bad as before.
intel e1000e driver :
root@riwiatom:# ethtool -i eth0
Maybe it is something external. But I can't explain why ping is stable < 1ms when I boot with some other distro from a stick and not with slack13.37 or slack14.0
