Subject: khugepaged cannot be freezed on 3.2-rc1
Date: Sun, 13 Nov 2011 14:42:35 +0000 [thread overview]
Message-ID: <1321195355.2020.10.camel@localhost.localdomain> (raw)
I am sorry if I've sent to wrong address. It seems that bug reporting
resources - bugzilla & "Reporting bugs for the Linux kernel" page - are
(still?) down. I followed the latter from web archive).
When I try to suspend the computer the khugepaged refuses to be
suspended:
