Public bug reported: [Impact] Need this patch in so a BIOS upgrade won't cause issues on HP laptops.
commit 1598bfa8e1faa932de42e1ee7628a1c4c4263f0a Author: Jorge Lopez <[email protected]> Date: Fri Oct 28 10:55:27 2022 -0500 platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded strange char "^@" which printed out every second and makes login nearly impossible. Also the below messages were shown both in console and journal/dmesg every second: usb 1-3: Device not responding to setup address. usb 1-3: device not accepting address 4, error -71 usb 1-3: device descriptor read/all, error -71 usb usb1-port3: unable to enumerate USB device Wifi is soft blocked by checking rfkill. When unblocked manually, after few seconds it would be soft blocked again. So I was suspecting something triggered rfkill to soft block wifi. At the end it was fixed by removing hp_wmi module. The root cause is the way hp-wmi driver handles command 1B on post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate that BIOS no longer controls the power for the wireless devices.
