full dmesg

Hallo,

starting with 6.10-rc1 I'm unable to suspend my laptop when the LAN cable is not connected. dmesg shows:

[42394.581194] e1000e 0000:00:1f.6: PM: pci_pm_suspend(): e1000e_pm_suspend [e1000e] returns -2
[42394.581205] e1000e 0000:00:1f.6: PM: dpm_run_callback(): pci_pm_suspend returns -2
[42394.581209] e1000e 0000:00:1f.6: PM: failed to suspend async: error -2
[42394.704458] PM: Some devices failed to suspend, or early wake event detected
[42401.167550] e1000e 0000:00:1f.6 eth0: Hardware Error

This doesn't happen when the lan cable is plugged in.

Full dmesg is attached with several scsessful suspend/resumes when connected and the last failed suspend when disconnected.

Can anyone confirm this?

I believe I'm seeing something similar that is the result of a commit added to 6.10.0-rc2. I've bisected it here. Perhaps it's the issue for you as well? https://bugzilla.kernel.org/show_bug.cgi?id=218940
Comment 3 Todd Brandt 2024-06-05 22:23:36 UTC
oh, I didn't notice you have a bisect commit as well, ok clearly not the same issue. Never mind.
Comment 4 Dieter Mummenschanz 2024-06-06 05:35:12 UTC
No you were right. They are related as a matter of fact. I've added the wrong commit id here.

I see this too with this NIC:

❯ lspci | grep Ethernet
00:1f.6 Ethernet controller: Intel Corporation Device 550b (rev 20)

A workaround is to rmmod e1000e (obviously only when you aren't using the NIC). I find that it suspends with the module unloaded.
