dmesg from the moment the kernel crashes

Hi, 
hopefully someone can help us out.. we're currently busy on a patch for ASUS ROG series notebooks on hid (asus-hid) level, and we're facing a strange behavior if we're calling asus_wmi_send_event. this issue reproducable causes a kernel crash...

The patch this is relaying on is: https://lkml.org/lkml/2020/9/23/1061

what we're doing:
we're trying to forward a raw event to an wmi event, which mostly works.. until you're pressing the key multiple times within a second (or slower but continously). 

as far as we digged through this might be caused by ACPI.. but we're really unsure.

it happend during calling `asus_wmi_send_event(drvdata, 0xae)`, pls see attached log.


maybe someone has a clou what we're doing wrong - or ist it a bug?


cheers.

as you already have a patch, why not submit the patch to the mailing list directly?

run ./scripts/get_maintainer.pl your-patch first
and submit your patch out.
Bugzilla is not a good place for people to review your patch.
Bug report closed.
