I had another go, trying to break into the merge commit, and it's slightly more precise, but still doesn't make any sense to me. # first bad commit: [3431e490b50356b56084305a2e93b3a980802b22] Merge branch 'acpi-scan' into acpi-pm Any ideas?

I'm running out of them... The parents of this merge are 5af310a8ee70 and 1dcc3d3362b0. Can you please check if the problem is present in any of them alone? If not, it is theoretically possible that the merge itself had introduced it (as this is not a trivial merge).

I guess this is related to https://github.com/hadess/iio-sensor-proxy/issues/82 There is some race between user space and iio. So the driver powerup never gets called back to power a hub during system boot. So the workaround was to add to systemd unit file for iio-sensor-proxy [Unit] After=multi-user.target Something changed timings in the kernel, which triggered this issue. I never got chance to root cause this.

I don't think it's simply "timings", or at least it's a big enough window of opportunity that I can reproduce the bug 100% of the time when not adding timeouts to iio-sensor-proxy's timeout. Putting the machine on suspend and resuming it also fixes the problem (for a machine I've been testing that can be suspended, it's not an option for all of them). > I never got chance to root cause this. Well, at least the root cause is limited to a single commit, shame it's a merge one. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

In fact this is a merge that doesn't change any code by itself (I thought it did, but that was not correct), so if that had been more than timings, you'd have seen breakage on at least one of the merged branches. Moreover, it merges the commits under 3431e490b503 back on top of material that went into 4.2, so if you only see the problem in 4.3 and later, this has to be the 3431e490b503 branch. Can you double check 3431e490b503 alone, please?

I don't understand what you're asking of me. I'm not a git master, and I've never had to deal with merge commits. Did you want me to run "git reset --hard 3431e490b503" and test the resulting kernel? I'm pretty sure that's equivalent what my 3 runs of bisection have done, and it failed.
