Could you rebuild kernel with CONFIG_PROVE_LOCKING option to discover locking related deadlocks? Then upload the log after reproduce the issue by shut down laptop with the new kernel. Also please attach the output of lsusb given it could be usb relevant. And it also would be helpful to try with latest noble kernel or recent upstream kernel, thanks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2061091 Title: Freezing user space processes failed after 20.008 seconds (1 tasks refusing to freeze, wq_busy=0) Status in linux-signed-hwe-6.5 package in Ubuntu: New Bug description: Sometimes, when trying to shut down or suspend my laptop, it gets stuck on the console screen. If I was suspending, it eventually gives up and goes back to the X session. During a shutdown it hangs forever and the only solution seems to be to force a reboot with Magic-SysRq.

So I guess there is some sort of deadlock in the USB subsystem which is causing all the other problems?
