http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=673 Summary: kernel BUG at arch/i386/mm/pgtable-xen.c:306 (sometimes causing a Panic) Product: Xen Version: 3.0.2 Platform: x86 OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Guest-OS AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: list@xxxxxxxxxx My setup was: I'm running a SMP machine (2 Opteron) with 6G of ram. No special parameters where set for the memory of dom0, so it took it all. Everything woked fine with one or two small domUs. Then I startet a domU that was supposet to take 5G of ram. (btw: I to start that domU twice, because dom0 didn't balloon fast enough). Now some bug claiming to be at arch/i386/mm/pgtable-xen.c:306 started to kick in in dom0. It caused some processes to terminate (especially it logged me off) and one time I even got a kernel-panic. The problem didn't reappear after I limited the memory of dom0 to 300M. Kernelversion is a xenified 2.6.16.20 from kernel.org. xen is 3.0.2 with pae-Support Distribution is a Ubuntu 6.06 Here comes some of the stuff I found in kern.log Jun 11 15:09:02 cipx1 kernel: [ 204.080696] ------------[ cut here ]------------ Jun 11 15:09:02 cipx1 kernel: [ 204.080795] kernel BUG at arch/i386/mm/pgtable-xen.c:306!
