Date: Fri, 06 May 2011 00:04:14 +0200 From: Thomas Sattler <tsattler@....de> To: Andrea Arcangeli <aarcange@...hat.com> CC: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: Re: iotop: khugepaged at 99.99% (2.6.38.X) It happened again: This time with 2.6.38.4 after 13 days uptime. In fact it was "13 days after last boot", since this machine is hibernated quite often. I waited only two minutes before I run 'reboot' as root. > Please next time can you run SYSRQ+t too in addition of SYSRQ+l? See http://pastebin.com/raw.php?i=XnXXfC40 (It seems to me SYSRQ+l did not work at all? And does also not work on 2.6.38.5?) see http://pastebin.com/raw.php?i=Zuv0VnUP for 'top/iotop' > You can run also a "ps xal" to see the actual scheduler task > state. I had no access to my mails and forgot to run 'ps xal'. :-( > If we understand what it is, it'll be easy to tell if it was already > fixed in 2.6.38.4 but I doubt unless it's not related to MM. Definitely not fixed in 2.6.38.4.
