[Xen-devel] infrequent kernel crash just before reboot
Hi All, Once in a while when i try to reboot my machine the kernel crashes, because it''s so infrequently i haven''t been able to capture it via a serial log yet. I have made 2 photographs from what''s left on screen from the oops.

Or any stray tapdisk processes?I was allready afraid for that, i also can''t give you that info, since i was not paying much attention, since rebooting goes well most of the time. I will try to keep an eye on it and hope i can report back again with more info.> Thanks, > J>> Machine is running : >> >> serveerstertje:~# xm info >> host : serveerstertje >> release : 2.6.32.15+xen-2.6.32.x-20100622-b >> version : #2 SMP Fri Jun 25 19:29:24 CEST 2010 >> machine : x86_64 >> nr_cpus : 6 >> nr_nodes : 1 >> cores_per_socket : 6 >> threads_per_core : 1 >> cpu_mhz : 3200 >> hw_caps : 178bf3ff:efd3fbff:00000000:00001310:00802001:00000000:000037ff:00000000 >> virt_caps : hvm >> total_memory : 8126 >> free_memory : 3958 >> node_to_cpu : node0:0-5 >> node_to_memory : node0:3958 >> node_to_dma32_mem : node0:2810 >> max_node_id : 0 >> xen_major : 4 >> xen_minor : 0 >> xen_extra : .1-rc4-pre >> xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 >> xen_scheduler : credit >> xen_pagesize : 4096 >> platform_params : virt_start=0xffff800000000000 >> xen_changeset : Tue Jun 22 07:31:14 2010 +0100 21226:7dcfdd45bc9e >> xen_commandline : dom0_mem=768M loglvl=all loglvl_guest=all >> cc_compiler : gcc version 4.3.2 (Debian 4.3.2-1.1) >> cc_compile_by : root >> cc_compile_domain : >> cc_compile_date : Tue Jun 22 23:48:22 CEST 2010 >> xend_config_format : 4 >> serveerstertje:~# >> >> >> kernel: >> commit 01d9fbca207ec232c758d991d66466fc6e38349e >> Merge: cfce2d4... 0a904db... >> Author: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> >> Date: Tue Jun 15 14:09:48 2010 +0100 >> >> Merge branch ''xen/next'' into xen/stable-2.6.32.x >> >> * xen/next: >> netback: minor code formatting fixup >> Netback: Set allocated memory to zero from vmalloc. >> xen/netback: linearise SKBs as we copy them into guest memory on guest-RX. >> xen: netback: drop frag member from struct netbk_rx_meta >> xen: netback: handle NET_SKBUFF_DATA_USES_OFFSET correctly >> xen: netback: Fixes for delayed copy of tx network packets. >> xen/gntdev: use spinlocks rather than rwsem for locking >> xen: Fix to hugepages to work around new PWT handling >> Fix compiler warning. >> xen/balloon: update ''page'' for each page >> >> >> >> -- >> Sander-- Best regards, Sander mailto:linux@eikelenboom.it _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
