Btw., Fedora has it enabled as of kernel 5.3.10 (see https://bugzilla.redhat.com/show_bug.cgi?id=1769465), and Ubuntu 19.10 appears to have it enabled in their 5.3 kernels.

I take it back: this does not appear to be screen-blanking related at all. Instead, it appears to be related to A) something causing massive numbers of acpi interrupt gpe07...

Btw., I traced this to the `acpi_remove_gpe_handler()` call taking a long time, and that in turn because it ends up calling `acpi_os_wait_events_complete()` which in turn calls `flush_workqueue(kacpid_wq);` and that is...

Thanks for the info. Unfortunately, the dmesg output you gave above is for the keyboard driver, which is separate from the touchbar driver. So can you show me the output...

Hmm, that `lsusb -t` output is very odd: there should be another 3 devices listed as children of the last item. For reference, this is what I see on my...

Oh, two more things: what machine/model are you on? And what is the output from ```sh ls -l /sys/bus/usb/devices/ ```
