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.
