I appreciate that you have been keeping things relatively simple and breaki= ng the information gathering into reasonable chunks. It took me embarrassingly long to figure out how to attach the files - but = at least they appear to be there now! Before starting I opened one terminal with dmesg -w And in another terminal I did=20 sudo sysctl kernel.sysrq=3D1 echo 'file drivers/acpi/ec.c +p' | sudo tee /proc/dynamic_debug/control As there is now more output into the dmesg window I decided to capture just= the system sitting alone through two pause events and captured that in my first upload #310145 Next I did the spamming requested (both l and w alternating until the pause ended) This is contained in attachment #310146 I noticed with the first spamming attempt that the new output ACPI messages happen in the dmesg window before the system actually pauses. So I did ano= ther spamming attempt but this time I tried to start spamming as soon as I saw t= he dmesg window start displaying the new ACPI messages. It is likely this file has data that starts earlier and personally I would start looking at this o= ne first. This is contained in attachment #310147 As always - let me know if you want more. --=20 You may reply to this email to add a comment.
