Public bug reported: [Impact] Intel AX201 firmware crashes or hardware RX ring buffer hangs after S3.
[Fix] Use new firmware from linux-firmware.git can solve the issue. [Test] WiFi works for each cycle of 1000 S3 cycles. [Regression Potential] Both Focal 5.4 and OEM 5.6 kernel use this firmware, so it might regress current 5.4 users. I did a smoke test with this firmware on Focal 5.4, and I didn't see any regression. Instead of cherry-pick the commit, only add the firmware needed for AX201 to minimize the regression risk. ** Affects: linux-firmware (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: linux-firmware (Ubuntu Focal) Importance: Medium Status: Confirmed ** Also affects: linux-firmware (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-firmware (Ubuntu) Status: New => Fix Released ** Changed in: linux-firmware (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-firmware (Ubuntu Focal) Importance: Undecided => Medium -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1900883 Title: Add new iwlwifi firmware to solve AX201 hang Status in linux-firmware package in Ubuntu: Fix Released Status in linux-firmware source package in Focal: Confirmed Bug description: [Impact] Intel AX201 firmware crashes or hardware RX ring buffer hangs after S3.
