russianneuromancer, can you check if the device you are seeing this with

also has a brcm43430 sdio wifi and if so if switching to:

Fixes this ?

Judging by this error message

[    7.744262] brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43241b4-sdio.txt failed with error -2

Lenovo Miix2 8 have brcm43241b4 sdio wifi. 

With brcmfmac43241b4-sdio.txt from NVRAM, as suggested here https://wireless.wiki.kernel.org/en/users/drivers/brcm80211 WiFi connection works for me with upstream Linux 4.12.4, but doesn't work with Linux 4.13rc1 and Linux 4.13rc3.

Yeah. There are three patches currently in wireless tree, maybe also in
netdev tree, which will probably be included in 4.13-rc4 fixing the
issue below.

Few connection attempts with Linux 4.13rc3 looks like this:

Hi,

When upgrading my devel environment to 4.13-rc1+ I noticed that
the brcm43430 sdio wifi on a Chuwi Hi8 plus stopped working:

jul 22 14:13:23 localhost.localdomain kernel: brcmfmac: brcmf_sdio_probe: Loading firmware brcm/brcmfmac43430-sdio.bin for chip 0000a9a6 rev 00000001

jul 22 14:13:23 localhost.localdomain kernel: brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012

jul 22 14:13:31 localhost.localdomain kernel: brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
<repeats>

The real culprit here seems to be:

jul 22 14:13:23 localhost.localdomain kernel: brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012

I've tried reverting allmost all changes under drivers/net/wireless/broadcom/brcm80211
as well as those under drivers/mmc, but that did not help.

Googling for the "Unknown mailbox data content" error found some Raspberry Pi 3
related comments where users report success with a different firmware version
from: https://android.googlesource.com/platform/hardware/broadcom/wlan/+/master/bcmdhd/firmware/bcm4343/

So I tried that as well as a version extracted from the Android install
on the tablet and both work fine, only the "version 7.45.41.26" which
happens to be the one in linux-firmware causes this problem, I've put
all (Linux build, not NDIS) versions I could find here:

http://jwrdegoede.danny.cz/brcm-firmware/

I've the feeling that the 7.45.41.26 version is a bit buggy / suspect to
certain timing problems and 4.13 just happens to trigger those timing
conditions...

russianneuromancer has reported seeing a similar problem with 4.13.
