Public bug reported:
Last night, I updated to kernel 6.8.0-100.100 from kernel 6.8.0-94.96
and immediately shut down the computer. Today I booted the computer,
read some things for a few minutes and tried to suspend, which failed
repeatedly. I had no such problem in the previous kernel.
journalctl reported the following lines as the source of the problem:
Feb 07 12:02:24 pm-cpp kernel: mt7925e 0000:83:00.0: Message 00020007 (seq 5)
timeout Feb 07 12:02:24 pm-cpp kernel: mt7925e 0000:83:00.0: PM:

0000:83:00.0: PM: failed to suspend async: error -110 Feb 07 12:02:24 pm-cpp
kernel: PM: Some devices failed to suspend, or early wake event detected
I am able to suspend by shutting down wifi and removing the mt7925e and
related kernel modules:
sudo nano /usr/lib/systemd/system-sleep/mt7925e-sleep
#!/bin/sh
case "$1/$2" in
pre/*)
/usr/bin/nmcli radio wifi off >/dev/null 2>&1 || true
/usr/sbin/modprobe -r mt7925e mt76_connac_lib mt76 >/dev/null 2>&1 || true
;;
post/*)
/usr/sbin/modprobe mt7925e >/dev/null 2>&1 || true
/usr/bin/nmcli radio wifi on >/dev/null 2>&1 || true
;;
esac
exit 0
The above, however, may give me problems resuming remote connections.
An alternative is to return to my older kernel, but that loses security
updates, I presume.
