Message-ID: <8347f3fb0805111721m57ba99e4l21df02d38ca3f41f@mail.gmail.com> Date: Sun, 11 May 2008 20:21:05 -0400 From: "Randy Johnson" <theraptor2005@...il.com> To: linux-kernel@...r.kernel.org Subject: 2.6.25.1: Kernel BUG at mm/rmap.c:669, General Protection Faults, and generic hard locks Hi, Recently moved from 2.6.22 up to 2.6.25.1 to solve some AHCI issues. Following this update, Matlab has caused numerous hard lockups. I've gotten lucky twice and been able to remote in and get the logs, which follow below. System is an AM2 with 6G ram installed, but booted with mem=3200M to circumvent some IOMMU issues. It is possible to eventually replicate the issue, but not with a specific sequence of activities that I've found. General activity from Matlab when it occurs is heavy disk IO (reading, no writting), and large memory consumption. Latest version of memtest86+ was run overnight and shows no issues. Any thoughts? -Randy Johnson log #1 Eeek! page_mapcount(page) went negative!
