I have fix this issue in OpenIntelWireless/itlwm project:
https://github.com/OpenIntelWireless/itlwm/commit/1fc63d576975d56578ce2048f00f83e7ca550d97
I am not sure if it is a hardware bug for newer intel wireless card, for
9560ac-cnvi and later Gen2 cards, MSI-X interrupt mode is enable by default,
Intel wireless drivers on linux/Windows are supported and using MSI-X interrupt
default, when rebooting to freebsd, iwm on freebsd only support MSI interrupt
but the hardware is configure as MSI-X, so the interrupt will never happened
and caused the issue.
Here are two solutions:
1. Implement MSI-X interrupt mode on iwm.
2. Disable MSI-X when init the hardware, and it is the solution what I am
using.
Thanks,
zxystd
