There should a block of error messages just above the panic, starting with a line that says "Eeek! page_mapcount(page) went negative!". Can you post those? Sure, here it is. Feb 10 08:00:34 tusdell kernel: Eeek! page_mapcount(page) went negative! (-1) Feb 10 08:00:34 tusdell kernel: page pfn = 0 Feb 10 08:00:34 tusdell kernel: page->flags = 400 Feb 10 08:00:34 tusdell kernel: page->count = 1 Feb 10 08:00:34 tusdell kernel: page->mapping = 0000000000000000 Feb 10 08:00:34 tusdell kernel: vma->vm_ops = generic_file_vm_ops+0x0/0x40 Feb 10 08:00:34 tusdell kernel: vma->vm_ops->fault = filemap_fault+0x0/0x328 Feb 10 08:00:34 tusdell kernel: vma->vm_file->f_op->mmap = generic_file_mmap+0x0/0x52 I might add that I have also just had this exact (as best I can see) error and that I notice that I am also running the VirtualBox drivers.

Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping It stopped to behave like that out of the blue as it started. I close that bug now since this kernel isn't current since a long time. |
