https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=286482 Bug ID: 286482 Summary: iwlwifi firmware prevents resume? (if_iwlwifi and if_iwx) Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: wireless@FreeBSD.org Reporter: pat@patmaddox.com I have an ax210 installed on my Thinkpad T14 AMD Gen 2. It appears that the iwlwifi firmware interferes with resume. I have not configured networking, and have added if_iwlwifi and if_iwx to devmatch_blocklist. I have debug.acpi.resume_beep=1. Without either of the drivers loaded, I can suspend with `acpiconf -s 3` and resume by pressing the power button. The beep sounds for a couple seconds, and the machine is fully resumed. If I load either `if_iwlwifi` or `if_iwx`, then the resume never completes - the beep plays indefinitely. Or at least, I let it run for a minute before I turn off the machine. My understanding is that if_iwx uses the iwlwifi firmware, which is why I suggest it may be an issue with the firmware. Setting debug.acpi.suspend_bounce=1 has interesting behavior. With if_iwlwifi loaded, `acpiconf -s 3` does a successful suspend/resume bounce. With if_iwx driver loaded, it hangs at the infinite beep. This is using the April stabilization week commit d4763484f911. -- You are receiving this mail because: You are the assignee for the bug.home | help
