Just fyi, crashed again yesterday morning 7:06am, similar backtrace. crash output for bt, ps, task & vm attached. I've since downgraded the drbd module version from 8.4.9-2 to 8.4.9-1, waiting for the crash to replicate again. And, as expected, the folks @RedHat closed the bug after reopening it as notabug, blaming drbd. Cheers, -- Adi Pircalabu -------------- next part -------------- A non-text attachment was scrubbed...
