It looks like I have things working now. I made sure avahi-daemon was also shut off, and a reboot seemed to clean things up. Network manager is now sticking to wlan0 and leaving eth0 alone, and I'm getting no errors from LinuxCNC.
I like this package of the laptop and the 7i93 very much. This will work well for my manufacturing class. My past efforts with various form-factor PC's with parallel ports were a pain with a class of 16 students. Now I just need to get Debian dual-booting along side of Windows on the laptops. Thanks for the help, Peter. -- Ralph ________________________________________ From: Ralph Stirling Sent: Tuesday, January 9, 2018 2:16 PM To: Enhanced Machine Controller (EMC) Subject: RE: [Emc-users] Mesa 7i93 with Dell E6430 laptop - Kernel version is: #1 SMP PREEMPT RT Debian 3.2.96-3 - OS is Debian Wheezy 7.11. - LinuxCNC is 2.7.11 uspace - /etc/network/interfaces has: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.1 hardware-irq-coalesce-rx-usecs 0 - all installed from instructions at: https://forum.linuxcnc.org/9-installing-linuxcnc/33596-mesa-7i93-7i33-7i37-easiest-install No changes to power source (plugged in the whole time), nor brightness changes. Now, running through things again after lunch, I find that eth0 no longer has an IP address, and I have a bunch of "eth0: no IPv6 routers present" errors in dmesg. I thought I had stopped those earlier by adding these lines to /etc/sysctl.conf: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 net.ipv6.conf.eth0.disable_ipv6 = 1 and running sysctl -p. It seems that was insufficient though. I think the real culprit, though, is that I see messages about eth0 in /var/log/syslog from NetworkManager. The debian documentation indicates that NetworkManager will leave alone interfaces specified in /etc/network/interfaces if manage=false in /etc/NetworkManager/NetworkManager.conf. It appears this isn't true though. Any tips on disabling NetworkManager for eth0, while allowing it to manage wlan0? Thanks again, -- Ralph ________________________________________ From: Peter C.

Second, have you disabled IRQ coalescing?
