Public bug reported: I'm not sure if this is the correct package, however, it's related to xen in general and linux-2.6.24-22-xen.
Ubuntu version is Ubuntu Hardy beta as of today. Circumstances are a bit complicated: The base system is an amd64 dual-core opteron running 2.6.24-12-xen on top of xen-3.2. I'm working on a script to automatically install different guests via template configurations. The domUs are running 2.6.22-14-xen from gutsy, because networking with the hardy xen kernel in domU is currently not working (https://bugs.launchpad.net/bugs/204010). That script basically sets up one or more LVM partitions, mounts them, debootstraps hardy with some predefined additional packages, runs a custom chrooted postinst-script, unmounts and then starts up the VM. Right after a reboot, this works without problems. However, when I shutdown the guest, remove the LVM volumes and run the script again, I'll get the following kernel Oops when localedef is started from debootstrap on configuration of the locales package. I can also install two almost identical guests, one after another, after a reboot without a problem. At last, I tried rebooting the system, starting up a guest VM, shutting it down again and then reinstalling it. No oops. Plan for tomorrow: Test the script again with dom0 running the gutsy xen kernel, too. ------------------------ snip [ 646.675038] Unable to handle kernel paging request at ffff8800741d5008 RIP: [ 646.675127] [<ffffffff80271e36>] iov_iter_advance+0x66/0x80 [ 646.675201] PGD 1fe5067 PUD 21e7067 PMD 2388067 PTE 0 [ 646.675251] Oops: 0000 [1] SMP [ 646.675289] CPU 0 [ 646.675321] Modules linked in: xt_physdev iptable_filter ip_tables x_tables bridge netloop blktap nbd video output sbs sbshc dock battery container ac blkbk netbk xenbus_be psmouse parport_pc lp parport ipv6 sr_mod cdrom button i2c_piix4 evdev k8temp i2c_core shpchp pci_hotplug pcspkr ext3 jbd mbcache pata_serverworks sg sd_mod ohci_hcd pata_acpi ehci_hcd tg3 sata_promise ata_generic usbcore ssb libata scsi_mod raid10 raid456 async_xor async_memcpy async_tx xor raid1 raid0 multipath linear md_mod dm_mirror dm_snapshot dm_mod thermal processor fan xennet xenblk [ 646.675844] Pid: 631, comm: localedef Not tainted 2.6.24-12-xen #1 [ 646.675882] RIP: e030:[<ffffffff80271e36>] [<ffffffff80271e36>] iov_iter_advance+0x66/0x80 [ 646.675946] RSP: e02b:ffff880059d83b10 EFLAGS: 00010246 [ 646.677898] RAX: 0000000000000000 RBX: 000000000000007f RCX: 0000000000000000 [ 646.677938] RDX: 0000000000000000 RSI: 000000000000007f RDI: ffff880059d83ba8 [ 646.677977] RBP: 000000000000007f R08: 0000000000000000 R09: 0000000000000000 [ 646.678016] R10: ffff8800741d5000 R11: 0000000000000000 R12: 0000000000000000 [ 646.678056] R13: 0000000000001000 R14: ffff88006cdedb48 R15: 0000000000000000 [ 646.678097] FS: 00007fd6f62096e0(0000) GS:ffffffff805b2000(0000) knlGS:0000000000000000 [ 646.678156] CS: e033 DS: 0000 ES: 0000 [ 646.678188] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 646.678228] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 646.678268] Process localedef (pid: 631, threadinfo ffff880059d82000, task ffff880064919800) [ 646.678328] Stack: ffffffff80273e0e 0000000000001000 ffff8800677db970 0000000000000000 [ 646.678404] ffff880059d83db8 0000000000000000 ffff880059d83d38 ffff880072585440 [ 646.678477] ffff88006cdedb48 ffffffff881cbac0 ffff88006cdeda38 ffffffff881cbac0 [ 646.678527] Call Trace: [ 646.678581] [<ffffffff80273e0e>] generic_file_buffered_write+0x1de/0x6e0 [ 646.678638] [<ffffffff881c852c>] :ext3:__ext3_journal_dirty_metadata+0x2c/0x70 [ 646.678699] [<ffffffff8023a97e>] current_fs_time+0x1e/0x30 [ 646.678741] [<ffffffff8027455f>] __generic_file_aio_write_nolock+0x24f/0x400 [ 646.678786] [<ffffffff802c38b6>] __getblk+0x26/0x250 [ 646.678826] [<ffffffff80274774>] generic_file_aio_write+0x64/0xd0 [ 646.678872] [<ffffffff881b8663>] :ext3:ext3_file_write+0x23/0xc0 [ 646.678915] [<ffffffff881b8640>] :ext3:ext3_file_write+0x0/0xc0 [ 646.678954] [<ffffffff8029d4ab>] do_sync_readv_writev+0xcb/0x110 [ 646.678998] [<ffffffff8024ca90>] autoremove_wake_function+0x0/0x30 [ 646.679038] [<ffffffff802a5b20>] permission+0xb0/0x160 [ 646.679076] [<ffffffff802a756f>] may_open+0xcf/0x290 [ 646.679112] [<ffffffff8029a0fc>] __kmalloc+0x13c/0x160 [ 646.679152] [<ffffffff8029dc4d>] do_readv_writev+0xfd/0x230 [ 646.679192] [<ffffffff8029bbca>] do_filp_open+0x3a/0x50 [ 646.679236] [<ffffffff8029e2c3>] sys_writev+0x53/0xc0 [ 646.679274] [<ffffffff8020c658>] system_call+0x68/0x6d [ 646.679312] [<ffffffff8020c5f0>] system_call+0x0/0x6d [ 646.679350] [ 646.679376] [ 646.679377] Code: 49 8b 52 08 49 89 d3 eb c4 4c 89 17 4c 89 4f 10 eb 99 0f 1f [ 646.679544] RIP [<ffffffff80271e36>] iov_iter_advance+0x66/0x80 [ 646.679584] RSP <ffff880059d83b10> [ 646.679615] CR2: ffff8800741d5008 [ 646.680368] ---[ end trace 39e94bb31c5ecce3 ]--- -------------------- snip ** Affects: xen-3.2 (Ubuntu) Importance: Undecided Status: New -- Kernel oops while localedef runs via debootstrap https://bugs.launchpad.net/bugs/207774 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
