Hi everyone. I have a FiiO Andes USB DAC that I use on my workstation, connected to a USB hub. The DAC is successfully recognized by the system, and I can play and listen to sound just fine.
After a seemingly random amount of time, the system completely locks up - the screen goes blank, the network becomes unresponsive, USB is dead - nothing works. This has happened both minutes after rebooting the system, and up to 7 days after rebooting the system.
Reconnecting the USB keyboard and HDMI monitor doesn't help. The only recourse is to powercycle the system.
Upon boot, there are absolutely no logs indicating pending or present issues - no kernel crash dumps, and nothing in syslog of interest (I also ship syslog to a remote machine and double-check there). This happens under minimal system load.
This issue was happening on 11.1-RELEASE, and is still happening on 11.1-STABLE.
System specs:
Any help is appreciated - at this point I've disconnected the DAC the fear of another system crash has spooked me.
