Hi All, See the individual commit messages for the what and why of this series only patch 1/2 is really necessary to fix the regression. The regression changes a theoretical race window in the hci_bcm IRQ handling into a real one and the first patch reverts the offending commit making the race window a theoretical thing again (we would need a 5 second stall in the right place to trigger it). The second patch in the series contains a simple fix closing the theoretical race window, this was tested with the regression still in place and it does successfully get things unstuck after hitting the race. I guess this can wait for 4.17, but I'm sending this out as a series as the patches were developed in tandem. This series was tested on an Asus T100CHI with a bcm43241b4 wifi/bt combo chip.
