I followed the following procedure to reproduce the issue, and will add some additional logs I made.
1. Boot the computer 2. Store dmesg in dmesg_first.txt 3. Store output of cat /proc/acpi/wakeup in wakeup_first.txt 4. Suspend using command pm-suspend (I can also close the lid) 5. Resume by pressing a key on the keyboard 6. Store dmesg in dmesg_second.txt 7. Store output of cat /proc/acpi/wakeup in wakeup_second.txt 8. Give commands sudo su echo devices > /sys/power/pm_test exit 9. Suspend using command sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" 10. System hangs 11. Reboot 12. Store dmesg in dmesg_secondboot.txt As requested somewhere I also add the output of lsusb -vnvn -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1552216 Title: Laptop hangs during second time it suspends To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552216/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
