(~_^) I am a professional Googler and I might have found a solution. Rmb the dmesg logs above where qubes show [ 4.742826] igb 0000:00:06.0: Using MSI interrupts. 1 rx queue(s), 1 tx queue(s) while Ubuntu show [13.700337] igb 0000:01:00.0: Using MSI interrupts. 2 rx queue(s), 2 tx queue(s) Apparently since 2013, the Intel note for igb drivers contains a troubleshooting section. The latest note: > Some systems have trouble supporting MSI and/or MSI-X interrupts. If your > system needs to disable this style of interrupt, the driver can be built and > installed with the command: > make CFLAGS_EXTRA=-DDISABLE_PCI_MSI install > Normally the driver will generate an interrupt every two seconds. If you're no > longer getting interrupts in cat /proc/interrupts for the ethX igb device, > then this workaround may be necessary. Couldn't figure out how to build the drivers (no network to install kernel headers) so more Googling pointed to a kernel option to disable msi. I used to command 'qvm-prefs sys-net kernelopts "pci=nomsi"' in dom0 and rebooted sys-net. Lo and behold, the interface has gotten an IP address!!! Ping is good and so far no network drop. Kinda lost track of how many changes I have made so I will do a fresh install and confirm again that disabling msi does the trick. > I'd find new > hardware if it was me. I would have did that if Qubes had some certified hardware. But I also wanted something small just for secure work and leave my larger desktop PC for more resource intensive apps and Windows stuff. This thing is literally the size of my hand. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
