SubjectRe: iotop: khugepaged at 99.99% (2.6.38.3)
Date
I am seeing exactly the same symptoms on my Lenovo T60 Core2 duo, 3GB RAM,
running Arch Linux i686 with Kernel 2.6.38.6. When I've heavily used Firefox for
a while, or used R with high memory usage (>1 GB), individual applications
become unresponsive, new processes fail to start and after a while the whole
system freezes. When it happens, iotop shows khugepaged and sometimes firefox at
99.99%.

I'd be happy to post information here when the problem occurs again. Anything
other than "cat /proc/zoneinfo"?
