I'm not sure it is is source of this issue but looks like it is related. If you open mentioned problematic commit in web ui: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.16.y&id=7cde9bf0731688896831f90da9fe755f44a6d5e0 And compare it with patch which is on "Link:" line from commit message: https://lore.kernel.org/r/20211125124605.25915-12-pali@xxxxxxxxxx You will see that diffs are different. In my original patch (which I sent to ML) is: mvebu_pcie_setup_hw(port); mvebu_pcie_set_local_dev_nr(port, 1); + mvebu_pcie_set_local_bus_nr(port, 0); But in git web ui is: mvebu_pcie_setup_hw(port); - mvebu_pcie_set_local_dev_nr(port, 1); + mvebu_pcie_set_local_dev_nr(port, 0); I do not know how it could happen. But local **device** number must be always set to 1 (see comment above code for explanation) and default value of local **bus** number should be 0 (as is in my original patch). So above patch in stable tree is broken. Bjorn & Greg: How do you want to handle this situation? Should I prepare special patch for stable which fix it? Or something else? Anyway, do you know how it could happen that patch was incorrectly auto-backported into stable? Differences between original and wrongly-modified patch looks very similar (both "bus" and "dev" keywords have same number of characters) and it was hard for me to see that there are differences. So probably overlooking could happen or maybe git or patch tools could do such small changes when doing backports? > I was trying to reproduce this issue on Turris Omnia but it looks like > that kernel v5.16.3 is totally broken and I'm not able to boot it.
