I was hoping not having to do that in my current setup. Yes, it works if I wire an ethernet connection to the Ultralight AVB.
#MAC DRIVER FOR MACKIE 802VLZ4 MAC#
I configured my router to assign a fixed ip address based on the UltraLite AVB's mac address. Plug your UltraLite AVB's ethernet interface in and see on your router which ip address it gets. I don't know if and how this works with Linux.

I guess on Windows and Mac they use ip-over-USB. The UltraLite AVB's mixer is accessible via web browser. On another machine with Core i5 those options had no effect at all. Adding "nowatchdog" lowers the realtime CPU displayed with Qjackctl from 44% to 37% on a given Qtractor project with many tracks and plugins compared to omitting "nowatchdog" on my Core i7 notebook computer. Hard to tell if there are some improvements when doing real work with Qtractor. I added your boot options and it still runs fine. I had no problems at all on my machine even without special boot options, maybe beause the Core i7 performs well.
Any kernel 5.8.X + Drumfix's module + setting USB host smp_affinity to use a single CPU + kernel boot options "acpi_irq_nobalance nowatchdog nohz=off intel_idle.max_cstate=1": rock solid 24 hours of sound without any issue. Really, I couldn't be happier, thanks again I hope it works for everybody and gives some direction for an official module in the future. I mean, by following the option 3 above I don't need to remove EHCI, or to unload other USB modules, or to use a specific kernel version, or to set CPU governor, or set queue_length, none of this is necessary. In terms of tweaking, everything else seems to make no difference.
Usable-ish with jack-plumbing doing persistent connections to outputs 1-2, 9-10 and 17-18.ģ. Any kernel 5.8.X + Drumfix's module + setting USB host smp_affinity to use a single CPU: from a few minutes to a few hours of sound, a very noticeable improvement.
Any kernel 5.8.X with default options + Drumfix's module: a few seconds of sound alternating with stops and artifacts. After exploring various tweak combinations I can summarize as follows:ġ. It's been two days running this device and trying to isolate what's causing the issues. Follow-up AVB Ultralite ESS with Drumfix's ua101.c module:
