[Bug 107325] Re: page_mapcount(page) went negative!
I have the same kernel problem. The machine is unstable, with random freezees every couple of days. The problem: - Machine is unstable. Max uptime is about two weeks. Hard freezees occur randomly, sometimes after less than day of use. Freeze is hard, nothing works: num lock does not change light, alt-ctrl-del does not work, picture is frozen on screen. Freeze also occurs when machine is not heavily loaded, even though heavy load seems to make it crash faster sometimes. - To test the problem, I changed hard disk, re-installed Ubuntu (6.06 LTS -> 7.04). I checked that hard drive and motherboard temperature is acceptable. Memory passed test. - Also, USB stopped to work after a kernel upgrade in Dapper (another bug). - Machine is unstable in both 6.06 LTS and 7.04, even though I have only seen the error in dmesg of 7.07. Attached dmesg is from 7.04. Some lines from dmesg: Eeek! page_mapcount(page) went negative! (-1) kernel BUG at mm/rmap.c:588! Trying to fix it up, but a reboot is needed Test setup: - sudo lshw: CPU AMD Athlon(tm) XP 2200+, BIOS American Megatrends Inc. 07.00T (04/02/01), Motherboard ECS M848A - uname -a: Linux *** 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux - Ubuntu 7.04, fresh install. ** Attachment added: "dmesg with page_mapcount negative error" http://librarian.launchpad.net/7418347/dmesg-eek.txt -- page_mapcount(page) went negative! https://bugs.launchpad.net/bugs/107325 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
