dmesg last time I boot
Description:
I recently received a new Lenovo Yoga Pro 7 14ASP9 and installed Linux on it
(kernel version 6.11.5). Most hardware functions as expected out of the box,
including Wi-Fi, Bluetooth, touchpad, keyboard backlight, audio, touchscreen,
and graphics card. However, the system fails to wake up after entering
sleep/suspend mode.
When the system goes into suspend, the power button indicator light continues
flashing, but attempting to wake it by pressing the keyboard or the power
button has no effect. The system remains unresponsive.
I also tried running sudo rtcwake -m mem -s 20 to test suspend mode, but the
system did not wake up after the specified 20 seconds.
Hardware Information:
Device Model: Lenovo Yoga Pro 7 14ASP9
Linux Kernel Version: 6.11.5
dmesg log: https://linux-hardware.org/?probe=414716466d&log=dmesg.1
Full Hardware Probe: https://linux-hardware.org/?probe=414716466d
Steps to Reproduce:
1.Put the device into suspend/sleep mode via the power menu or by using sudo
rtcwake -m mem -s 20.
2.Wait for the device to enter suspend, as indicated by the flashing power
button light.
3.Attempt to wake the device by pressing any key or the power button.
Expected Behavior:
The device should resume from suspend mode, with the display and other system
functions restored to a usable state.
Actual Behavior:
The device remains unresponsive, with only the power button indicator flashing.
The system does not respond to key presses or the power button, requiring a
forced reboot to recover.
Additional Notes:
1.This issue has been observed consistently with kernel version 6.11.5.
2.No errors or warnings related to this behavior appear in the logs leading up
to suspend.
