Message-ID: <20141104232027.GO13232@auth.logic.tuwien.ac.at> Date: Wed, 5 Nov 2014 08:20:27 +0900 From: Norbert Preining <preining@...ic.at> To: linux-kernel@...r.kernel.org Subject: khugepaged / firefox going wild in 3.18-rc Dear all, (please Cc) since 3.18-rc started, regularly, but unpredictably, firefox (Debian iceweasel) goes completely boom to 100% CPU, and there is also a kernel task khugepaged doing the same. I need to kill firefox, or better the X session to get it back to normal. THe logs don't show any strange output top's top process: 27021 norbert 20 0 1351536 449868 88788 R 100.4 5.6 4:46.16 iceweasel 35 root 39 19 0 0 0 R 100.0 0.0 2:41.10 khugepaged Switching back to 3.17 does Not* exhibit the same behaviour. Is this a bug in Firefox/Iceweasel, or is there something luring in the kernel. All the best Norbert ------------------------------------------------------------------------ PREINING, Norbert http://www.preining.info JAIST, Japan TeX Live & Debian Developer GPG: 0x860CDC13 fp: F7D8 A928 26E3 16A1 9FA0 ACF0 6CAC A448 860C DC13 ------------------------------------------------------------------------ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
