Thanks! I tried this and still no success. Given I tried unloading the ath12k module and had still seen this issue I suspect this is lower level which may require help from a Qualcomm dev. I also tried disabling hardware in the BIOS (to try to help single out the issue) but anything I tried resulted in system not booting properly. Do you think it's worth I send a small summary to the kernel mailing list? Thanks! :)
## Additional Details I'll include two tests here, first where I sleep and we still see the issue, second where I unload the potentially suspect modules and still see the issue. It's only about 200 lines so I'll paste here instead of attaching (I hope that's okay). # Kernel version ``` $ sudo uname -a Linux [HOSTNAME] 6.17.0-6-generic #6-Ubuntu SMP PREEMPT_DYNAMIC Tue Oct 7 14:22:06 UTC 2025 aarch64 GNU/Linux $ sudo lsb_release -a No LSB modules are available.
