[Resend in Plain Text] Hello Thomas, Hope you are doing well. I am Chaitanya from the linux graphics team in Intel. This mail is regarding a regression we are seeing in our CI runs[1] on linux-next repository. Since the version next-20241120 [2], we are seeing the following regression ````````````````````````````````````````````````````````````````````````````````` <4>[ 19.990743] Oops: general protection fault, probably for non-canonical address 0xb11675ef8d1ccbce: 0000 [#1] PREEMPT SMP NOPTI <4>[ 19.990760] CPU: 21 UID: 110 PID: 867 Comm: prometheus-node Not tainted 6.12.0-next-20241120-next-20241120-gac24e26aa08f+ #1 <4>[ 19.990771] Hardware name: Intel Corporation Arrow Lake Client Platform/MTL-S UDIMM 2DPC EVCRB, BIOS MTLSFWI1.R00.4400.D85.2410100007 10/10/2024 <4>[ 19.990782] RIP: 0010:power_supply_get_property+0x3e/0xe0 ````````````````````````````````````````````````````````````````````````````````` Details log can be found in [3]. After bisecting the tree, the following patch [4] seems to be the first "bad" commit ````````````````````````````````````````````````````````````````````````````````````````````````````````` Commit 49000fee9e639f62ba1f965ed2ae4c5ad18d19e2 Author: Thomas Weißschuh <mailto:linux@xxxxxxxxxxxxxx> AuthorDate: Sat Oct 5 12:05:03 2024 +0200 Commit: Sebastian Reichel <mailto:sebastian.reichel@xxxxxxxxxxxxx> CommitDate: Tue Oct 15 22:22:20 2024 +0200 power: supply: core: add wakeup source inhibit by power_supply_config ````````````````````````````````````````````````````````````````````````````````````````````````````````` This is now seen in our drm-tip runs as well. [5] Could you please check why the patch causes this regression and provide a fix if necessary? Thank you. Regards Chaitanya P.S. We could not revert the patch cleanly and therefore we are yet to verify the bisect but we are currently working on it. [1] https://intel-gfx-ci.01.org/tree/linux-next/combined-alt.html?
