Thank you. But now I know the fix series by Thomas is available. I prioritize the evaluation of the fix series. Later on, I will try disabling the static-keys if it is required. > > And Thomas Gleixner posted an alleged fix to the CID issue here: > > https://lore.kernel.org/lkml/[email protected]/ > > Please let him know whether or not it helps. Good to see this fix candidate series, thanks :) I have set up the patches and started my regular test runs. So far, the hangs have been observed once or twice a week. To confirm the effect of the fix series, I think two weeks runs will be required. Once I get the result, will share it on this thread and with Thomas.
