Hi Fengguang, Reproduced with your config and script. Working on locating the cause...
Thanks, -Artem -----Original Message----- From: Fengguang Wu [mailto:fengguang...@intel.com] Sent: Wednesday, July 30, 2014 7:08 AM To: Artem Fetishev Cc: Jet Chen; Su Tao; Yuanhan Liu; LKP; linux-kernel@vger.kernel.org Subject: [x86] BUG: unable to handle kernel paging request at ffff880012770000 Hi Artem, FYI, this bisect has noise errors, so I'm not sure if it's a correct bisect. git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit 825600c0f20e595daaa7a6dd8970f84fa2a2ee57 Author: Artem Fetishev <artem_fetis...@epam.com> AuthorDate: Fri Mar 28 13:33:39 2014 -0700 Commit: Linus Torvalds <torva...@linux-foundation.org> CommitDate: Fri Mar 28 13:56:58 2014 -0700 x86: fix boot on uniprocessor systems On x86 uniprocessor systems topology_physical_package_id() returns -1 which causes rapl_cpu_prepare() to leave rapl_pmu variable uninitialized which leads to GPF in rapl_pmu_init(). See arch/x86/kernel/cpu/perf_event_intel_rapl.c. It turns out that physical_package_id and core_id can actually be retreived for uniprocessor systems too. Enabling them also fixes rapl_pmu code.
