s3 sleep resume - network (wlan) drops, ntpd failure

S

spulick

Hi there,

I've just got FreeBSD 15 going on a Thinkpad T14 Gen1. It's mostly been great, except that there seems to be some issue with connecting to WiFi on waking from S3 sleep.

uname -a
FreeBSD dormouse 15.0-RELEASE-p9 FreeBSD 15.0-RELEASE-p9 GENERIC amd64

I've explored other threads and can confirm from the logs that /etc/rc.resume is being triggered. The logic currently calls /usr/local/sbin/auto-network-restart. I've been able to manually trigger the auto-network-restart script and intermittently get it to connect.

I've tried to use sleep of various time lengths to let the hardware to "settle" based on recommendations on other threads.

I use the iwlwifi0 driver and can confirm that wlan0 is the interface.

I would appreciate and love any help in fixing this. Please advice on if any more information is necessary.

This seems to be fixed on 16.0-CURRENT only, for the time being.

At the time of this writing "LinuxKPI: 802.11 suspend/resume: fix the is_pci_dev check"

has not landed on 15.1-STABLE (aka stable/15)
has not landed on 15.1-RC2 (aka releng/15.1)

At the time of this writing "LinuxKPI: 802.11: add support for suspend/resume"

has landed on 15.1-STABLE (aka stable/15)
has not landed on 15.1-RC2 (aka releng/15.1)

To avoid development snaptshot 16.0-CURRENT, wait for 15.1-RELEASE. The fixes should be merged until then.

In the meantime try workaround:
