Title:
Recurring problem with BT and WiFi from intel AC9560, problem with USB
1-10, not detected.
Status in linux-hwe-6.11 package in Ubuntu:
Confirmed
Bug description:
Bug Description: CNVi device fails to initialize Wi-Fi and Bluetooth
under Linux
System: ASUS ZenBook UX450FDX Kernel Versions Tested:
6.5.0-25-generic, 6.11.0-29-generic Firmware: linux-firmware
20240318.git3b128b60-0ubuntu2.14 Wi-Fi Module: Intel Wireless-AC 9560
Issue Summary: The integrated CNVi (Wi-Fi + Bluetooth) module fails to
initialize. The iwlwifi driver loads firmware
(9000-pu-b0-jf-b0-46.ucode) but throws INIT ucode -110 errors.
Additionally, ACPI shows duplicate entries such as AUSB, AUSO, and
SRB, triggering errors like AE_ALREADY_EXISTS. Attempts to decompile
ACPI tables via iasl fail due to unterminated quoted strings and
invalid fields (e.g. 0CC0).
Log Highlights:
iwlwifi 0000:00:14.3: Failed to start INIT ucode: -110
iwlwifi: Microcode SW error detected. Restarting...
UMAC dump shows DEADBEEF and invalid state
ACPI disassembly fails with 200+ errors
What I’ve Tried:
Switching firmware version from 46 to 38 → no success
Booting older kernel (6.5.0) → fails to initialize
Extracted ACPI via acpidump, iasl → failed to parse DSDT due to
malformed syntax
Firmware BT (ibt-19-0-4.sfi/ddc) present but BT does not activate
