Hello List, my Debian Lenny DomU sometimes crashes after a live migration. Here is what i get on the console: WARNING: at arch/x86/kernel/microcode_core.c:453 mc_sysdev_resume+0x28/0x52() Pid: 4, comm: migration/0 Not tainted 2.6.35.4 #5 Call Trace: [<ffffffff81039fec>] ? warn_slowpath_common+0x73/0x87 [<ffffffff81068701>] ? cpu_stopper_thread+0x13d/0x16e [<ffffffff810244a9>] ? mc_sysdev_resume+0x28/0x52 [<ffffffff8126596c>] ? __sysdev_resume+0x68/0xb5 [<ffffffff81265a15>] ? sysdev_resume+0x5c/0x97 [<ffffffff811fc99e>] ? xen_suspend+0xb8/0xbe [<ffffffff810687a5>] ? stop_machine_cpu_stop+0x73/0xa9 [<ffffffff81068732>] ? stop_machine_cpu_stop+0x0/0xa9 [<ffffffff810686a7>] ? cpu_stopper_thread+0xe3/0x16e [<ffffffff8138d0d7>] ? schedule+0x4f4/0x5be [<ffffffff810685c4>] ? cpu_stopper_thread+0x0/0x16e [<ffffffff8104cd69>] ? kthread+0x75/0x7d [<ffffffff810097a4>] ? kernel_thread_helper+0x4/0x10 [<ffffffff81008ba3>] ? int_ret_from_sys_call+0x7/0x1b [<ffffffff8138ee9d>] ? retint_restore_args+0x5/0x6 [<ffffffff810097a0>] ? kernel_thread_helper+0x0/0x10 ---[ end trace f89d7f3ec5f33611 ]--- PM: early resume of devices complete after 0.001 msecs PM: resume of devices complete after 0.001 msecs My Dom0 is Debian Squeeze with a 2.6.32.24-pvops kernel. Any idea? Thanks, Mario _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
okay, it may be a bad idea to not sync the swap disk with drbd. My migration from ServerA to ServerB now works great, but when i try to migrate back from ServerB to ServerA i get this: WARNING: at arch/x86/kernel/microcode_core.c:453 mc_sysdev_resume+0x28/0x52() Pid: 6, comm: migration/0 Tainted: G W 2.6.36 #1 Call Trace: [<ffffffff8103a5c4>] ? warn_slowpath_common+0x73/0x87 [<ffffffff8106e901>] ? cpu_stopper_thread+0x131/0x168 [<ffffffff81026461>] ? mc_sysdev_resume+0x28/0x52 [<ffffffff812678d4>] ? __sysdev_resume+0x68/0xb5 [<ffffffff8126797d>] ? sysdev_resume+0x5c/0x97 [<ffffffff811fb165>] ? xen_suspend+0xb8/0xbe [<ffffffff8138d56e>] ? _raw_spin_lock_irq+0x7/0x1c [<ffffffff8106e9ab>] ? stop_machine_cpu_stop+0x73/0xa9 [<ffffffff8106e938>] ? stop_machine_cpu_stop+0x0/0xa9 [<ffffffff8106e8ad>] ? cpu_stopper_thread+0xdd/0x168 [<ffffffff8138bd01>] ? schedule+0x64e/0x6f4 [<ffffffff8106e7d0>] ? cpu_stopper_thread+0x0/0x168 [<ffffffff8104f5fa>] ? kthread+0x7a/0x82 [<ffffffff8100a7a4>] ? kernel_thread_helper+0x4/0x10 [<ffffffff81009ba3>] ? int_ret_from_sys_call+0x7/0x1b [<ffffffff8138d95d>] ? retint_restore_args+0x5/0x6 [<ffffffff8100a7a0>] ? kernel_thread_helper+0x0/0x10 ---[ end trace 6d450e935ee1897f ]--- PM: early resume of devices complete after 0.001 msecs PM: resume of devices complete after 0.001 msecs Setting capacity to 20971520 Setting capacity to 2097152 Setting capacity to 20971520 Any idea?! :-) Cheers, Mario On Wed, Oct 27, 2010 at 11:49 AM, ml ml <mliebherr99@googlemail.com> wrote:> Hello List, > > my Debian Lenny DomU sometimes crashes after a live migration.

Debian Lenny kernel for Xen is really bugly, I spent on them few months and give up. As fast and dirty solution - use native centos kernel with native centos initrd and kill nash from rc.local - in this mode it works somehow.
