Since I installed the latest Debian updates yesterday (udev, systemd, ...) I can't put my Debian 9/KDE machine to sleep. It wakes up immediately after suspending (systemctl suspend
).
/var/log/syslog has the following:
..Stopping disk
parport_pc 00:01: disabled
e1000e: EEE TX LPI TIMER: 00000011
dpm_run_callback(): usb_dev_suspend+0x0/0x20 [usbcore] returns -16
PM: Device usb1 failed to suspend async: error -16
PM: Some devices failed to suspend, or early wake event detected
parport_pc 00:01: activated
..Starting disk
..
rtc_cmos 00:07: System wakeup disabled by ACPI
There were also some other messages at other tries such as a wlan-related "driver in IPS". But no matter what I try I always get the exact same message:
PM: Device usb1 failed to suspend async: error -16
What I tried so far
- Removing my wlan driver with
sudo rmmod
,sudo modprobe -r
andsudo dkms remove
. Couldn't put it to sleep after doing that. Also the module always gets loaded again after rebooting after "successfully" removing it (it's also not shown inlsmod
anymore). I have reinstalled it with dkms now. - Disconnecting all USB devices except of my keyboard to suspend the machine and disconnecting all USB devices except of my mouse to suspend the machine and immediately disconnecting the keyboard/mouse after suspending it.
Any other ideas what I should try? I find it strange that it displays that usb error even though all usb devices are disconnected.
