https://bugzilla.suse.com/show_bug.cgi?id=1221734 Bug ID: 1221734 Summary: RTL8723BE cannot initialize mac after suspend or loss of AP Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: x86-64 OS: openSUSE Leap 15.5 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel:Drivers Assignee: kernel-bugs@suse.de Reporter: owinebar@gmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- I am using Leap 15.5 on an old ASUS laptop, model R541U. The wifi was working fine when I initially installed Leap 15.4 as the sole OS around April 2023. The wifi started acting flaky in September 2023, but I didn't pay much attention because it has been working. I finally took the time to try to get it working again. I set the power save parameters off, the debug_mask to 0xFFFFFFFFFFFFFFFF, and the debug_level to 5. I also set NetworkManager to use a permanent MAC address for wlan0 because there the error seemed to be associated with a message "Init MAC" failed. The device still fails in 2 situations, and reports the "Init MAC" error. The first is after suspending the laptop. Presumably the power save from the suspend is not dependent on the driver power save parameters, so it attempts and fails to reinitialize the wlan0 device. With debug level at 5, I see rtlwifi report "init MAC Fail as power on failure", the the "Init MAC failed" message from rtl8723be, then the message "Failed to config hardware!" from rtlwifi. The other failure arises when the connection to the AP is lost for 10s (at least that's what it reports) after rebooting with no intervening suspend. In the latter case, there are a lot of messages "Waiting for FW read clear HMEBox(0)!!! 0x130 = ff". The "Init MAC failed" message first appears in my messages file dated 2023-09-11. The previous rolled messages file is dated 2023-09-08. Looking at the zypp/history log, I evidently updated the kernel from 5.14.21-150400.24.74 to 5.14.21-150400.24.81, somewhere around August 31 or September 6 of 2023. I only updated the distribution on the laptop to 15.5 recently. -- You are receiving this mail because: You are on the CC list for the bug.
