hwinfo --all output

Since about a month my notebook fails to suspend to ram. It takes a couple of
attempts
to suspend and eventually it succeeds, though at times when trying too soon
after the
previous attempt the system hangs.

I found this in the logs, perhaps it's related:
kernel: PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 [usbcore] returns -16
kernel: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x140 returns -16
kernel: PM: Device 0000:00:14.0 failed to suspend async: error -16
kernel: PM: Some devices failed to suspend, or early wake event detected
