Usually after a suspend, but sometimes in the middle of use, i find this sys-net-bsd completely unresponsive, the cpu balloons to 98% and the only thing i can do is kill it and restart. This happens a few times a day.
I tried to update the kernel, firmware etc… but it continues. I increased ram and:
sysctl machdep.lidaction=0
The WIFI driver is for the intel: iwm0, but as the whole VM freezes I suspect this is something on the xen / Qubes side. The build is exactly as the op.
i can see nothing in dmesg / var/log/messages just the usual rebooting messages.( on the Bsd side)
