Severity: important

Control: found -1 6.10.6-1~bpo12+1

Hi,

on my Lenovo Thinkpad T16 Gen 3, suspend does not work with recent
kernels. The laptop is running bookworm/amd64 with kernel (-amd64
flavor) and firmware from bookworm-backports or trixie (due to
hardware support).

Suspend works with 6.9.7-1~bpo12+1 (haven't tried 6.9.10-1~bpo12+1) but
fails with 6.10/6.11 kernels:

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

There is no ethernet cable connected. (Only used for the initial install
when wifi wasn't working yet.)
