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.
