[Fix] Proposed firmware upstreamed as: * 2afd1423e476 ("rtw89: 8852b: update fw to v0.29.29.5") * 7a916315fb28 ("rtw89: 8852b: update fw to v0.29.29.4") * 02df6e4f03c0 ("rtw89: 8851b: update fw to v0.29.41.3") [Test Case] 1. Install Ubuntu 22.04 on SUT with RTL8851BE / 8852BE Wlan card 2. Connected BT KB/MS, and then connected WIFI, select an AP to connect 3. Check BT mouse/keyboard, mouse movement, keyboard key pressing not respond smoothly. [Where problems could occur] This updates opaque firmware blobs, so anything could happen. With verifications from multiparties, it improves the stability and no other problem found so far. [Other Info] On Lunar, we don't have RTL8851BE enabled, so the related commits are omitted. On Mantic and oem-6.5/jammy, we have both. ========== original bug report ========== 1.Install Ubuntu 22.04 on SUT with RTL8851BE / 8852BE Wlan card 2.Connected BT KB/MS,and then connected WIFI, select an AP to connect 3.Check BT mouse/keyboard, mouse movement, keyboard key pressing not respond smoothly.
