fix-suspend-scheduler-v2 fix-suspend-scheduler-revert-affinity-part s3-timerirq All of these fixes have been proposed to the xen-devel list, but have not yet been accepted, for one reason, or another.And I don't think comments on them have seen follow-ups. Jan I guess it's worth bringing this up again;s3-timerirq: this was empirical hack which for some reason is needed on stable 4.2 we use, but not on latest unstable, didn't really investigate further since it appeared fixed later on anyway.. fix-suspend-scheduler/revert-affinity: the big objection here was the part which reverts one of the hunks in Keir's commit. I tried for quite few days to find a working fix which does not do this revert using posted suggestions, but was not succesfull: - there was a crash in xen scheduler, which was fixable using your suggestion of masking softirqs during s3 (ugly) - there was also a crash in xen acpi cpufreq driver, which was similarily fixable using a bandaid s3 condition (ugly) - unfortunately this turned out to not be all, xen did not crash anymore at this point but dom0 kernel did around the time it enables cpus, in multiple places: at this point I didn't have a good explanation for it, my opinion of aggravating hunk was rather low, so I uttered a hearty curse and stuck a revert into private patchqueue. The dom0 kernel crashes were as follows: 1) [ 60.657751] Enabling non-boot CPUs ...
