BTW, could you try to apply the attached patch file on top of the v8 patch series to see if it can fix the hang problem? Ran the benchmarks with the fix and I am not seeing hang so far. ebizzy improvements. 0.5x 2.7345 1x -10.6593 1.5x 35.6962 2x 88.0461 dbench improvements 0.5x 3.2428 1x 1.1514 1.5x 5.5071 2x 23.8700 ( I will have to restest on ebizzy 1x reression but overall performance numbers look good). Baseline was 3.14-rc8 without any of the qspin patch series.Does the baseline have PV ticketlock or without any PV support? baseline had PV ticketlock enabled. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
