Subject: khugepaged / firefox going wild in 3.18-rc
Date: Wed, 5 Nov 2014 08:20:27 +0900 [thread overview]
Message-ID: <20141104232027.GO13232@auth.logic.tuwien.ac.at> (raw)
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
