dmesg log

I'm opening this case to follow up the issue on https://bugs.freedesktop.org/show_bug.cgi?id=105130.
Machine is an IVB.

based on the above:

$ lspci -s 0000:00:1d.0

00:1d.0 USB controller

from dmesg:

[  133.856853] pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -16
[  133.856863] dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -16
[  133.856873] PM: Device 0000:00:1d.0 failed to suspend async: error -16
[  133.957621] hp_wmi: Unknown event_id - 14 - 0x0
[  134.341326] PM: Some devices failed to suspend, or early wake event detected

Also this seems like https://bugs.freedesktop.org/show_bug.cgi?id=103520, which was closed as fixed but never was found what actually fixed it.
