kernel log of suspend/resume cycles illustrating the issue
Kernel logs showing brcmfmac timeout on boot |
||
Additionally, I install Windows 10 and all the drivers and was able to power-cycle and suspend-resume cycle many times without observing this issue, so the platform is reliable. Interestingly, updating to BIOS 1.2.25 makes this issue somewhat acute in Linux across all kernels, including the stock 4.8.0-52 Ubuntu 16.04.2 kernel. I observe the same 'Timeout on response for query command' signature, but at 70% of boots. Booting into windows, wireless works every time and across suspend/resume cycles.

Kernel logs showing brcmfmac timeout on boot
adding Intel on a BRCM bug isn't exactly useful :) In the failure case, if I 'modprobe -r brcmfmac; sleep 1; modprobe brcmfmac', we observe:
brcmfmac 0000:02:00.0: enabling device (0000 -> 0002)
brcmfmac: brcmf_chip_recognition: chip backplane type 15 is not supported
brcmfmac: brcmf_pcie_probe: failed 14e4:43ba
This comes from:
socitype = (regdata & CID_TYPE_MASK) >> CID_TYPE_SHIFT
...
brcmf_err("chip backplane type %u is not supported\n", socitype);
where CID_TYPE_MASK is 0xf0000000. This suggests the read32 (which maps to ioread32) returned all ones (0xffffffff), which may suggest power is gated to part of the device.
Resetting the device via PCIe reset makes it work every time (including on BIOS 1.2.25): echo 1 >/sys/bus/pci/devices/0000:02:00.0/remove sleep 1 echo 1 >/sys/bus/pci/rescan This tends to suggest there is some missing/incorrect register programming in the driver.

Tried it already, but seems like it have some differences in init/settings with the linux one. Maybe it is possible to copy only the proprietary part of it. Currently used version: 7.35.177.61 (r598657) FWID 01-ea662a8c Attached version: 7.35.240.55 (r609579) FWID 01-89725025 https://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=JKRJ9 The firmware itself resides in Drivers/WinThresh/WL/x64/43602a1rtecdc.bin |
Created attachment 256915 [details] kernel log of suspend/resume cycles illustrating the issue I find around 10% of boots or suspend/resume cycles, the brcmfmac driver will fail to work as expected. On a resume or boot that fails, we see: brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command This is reproducible on a clean and updated install of Ubuntu 16.04.2 with the mainline 4.11.4 kernel on a Dell XPS 15 9550 with BIOS 1.2.21. I have attached a log of suspend/resume cycles illustrating the issue.
