I have some interesting issues with a new MBP (13", early 2015, bought early 2016, corporate reseller) which seem to be connected to some internal bus. In all fairness I have not delved into the exact layout of the MBP-mobo to figure out specifics, but it seems like whenever WiFi, webcam or USB come under heavier lasting loads most peripherals needs to be reset (including WiFi).
My minimal working example of the issue is watching twitch.tv with the flash-player (ie flash enabled in safari). This is enough to kill the WiFi within a minute.
I've also gotten the same effect by just using the webcam to record me talking for a couple of minutes, although this does not always happen. Same thing with listening on music with a headset. Regardless of how the "issue" is initiated, only the WiFi shows up in the log, and only the wl0 interface, but most USB-devices need to be physically reconnected for the computer to detect them again.
Examples from the log:
28/02/16 23:16:54,000 kernel[0]: ARPT: 3355.995355: wl0: fifo 0: data error
28/02/16 23:16:54,000 kernel[0]: ARPT: 3355.995364: wl0: fatal error, reinitializing, total count of reinit's[9], @'wlc_bmac_fifoerrors':9913
Example from log when usb (audio in this case) goes down:
29/02/16 09:34:05,000 kernel[0]: WARNING: AppleUSBAudio has detected that a connected USB audio device is sending too much audio data.
29/02/16 09:34:05,000 kernel[0]: WARNING: This USB audio device may not function properly. Please notify the device manufacturer.
Example from log when webcam causes usb / wifi / webcam down:
28/02/16 23:16:52,290 AppleCameraAssistant[4824]: FrameReceiverMessageCallback: KernelFrameDropNotification (Frames are dropping). The firmware is not returning buffers quickly enough.
Has anyone encountered something similar? Could you fix it somehow?
To clarify, either of these event can cause this "south bridge" shutdown / reset, which reinitiates the WiFi, reinitiates USB-ports and shuts off the webcam.
Additional info:
- This happens regardless of AP.
- It is much harder to reproduce when on ethernet/usb-adapter.
- WiFi + headset + webcam (+ skype) resets "the bus" in under a minute.
- Today it happened on average every 12 minutes.
- corecaptured (the deamon for logging errors) catches it, but only that the wifi driver goes down.
I've tried
- SMC reset multiple times
- NVRAM reset multiple times
- different users
- w/o peripherals
- w/o power cord
If needed I can pastepin a lot of logs.
Adding lsmod / kextstat output as well. How can I verify that I have the correct version?
