Hi Wei, Just back from holiday i tried running a new xen-unstable and linux kernel (current Linus his tree + Konrad's last pull request merged on top). I saw a thread and patch about a bug_on in increase_reservation ... i'm seeing the splat below in dom0 when guests get started. I run with dom0 mem restricted (dom0_mem=1536M,max:1536M) and with autoballoon="auto" in xl.conf, so afaik that should essentially disable ballooning ? -- Sander Sep 10 16:42:47 serveerstertje kernel: [ 142.698231] BUG: using smp_processor_id() in preemptible [00000000] code: blkback.1.xvdb/9138 Sep 10 16:42:47 serveerstertje kernel: [ 142.703854] caller is decrease_reservation+0x260/0x3b0 Sep 10 16:42:47 serveerstertje kernel: [ 142.709355] CPU: 0 PID: 9138 Comm: blkback.1.xvdb Not tainted 3.11.0-20130910 #1 Sep 10 16:42:47 serveerstertje kernel: [ 142.714956] Hardware name: MSI MS-7640/890FXA-GD70 (MS-7640) , BIOS V1.8B1 09/13/2010 Sep 10 16:42:47 serveerstertje kernel: [ 142.720714] 0000000000000000 ffff880058905958 ffffffff81a3e4e2 0000000000000006 Sep 10 16:42:47 serveerstertje kernel: [ 142.726541] ffff880058905fd8 ffff880058905988 ffffffff81415725 ffff88005175a000 Sep 10 16:42:47 serveerstertje kernel: [ 142.732317] 0000000000000001 0000000000000000 ffffea000145d680 ffff8800589059f8 Sep 10 16:42:47 serveerstertje kernel: [ 142.738068] Call Trace: Sep 10 16:42:47 serveerstertje kernel: [ 142.743785] [<ffffffff81a3e4e2>] dump_stack+0x4f/0x84 Sep 10 16:42:47 serveerstertje kernel: [ 142.749525] [<ffffffff81415725>] debug_smp_processor_id+0xe5/0x100 Sep 10 16:42:47 serveerstertje kernel: [ 142.755291] [<ffffffff814a6bc0>] decrease_reservation+0x260/0x3b0 Sep 10 16:42:47 serveerstertje kernel: [ 142.761215] [<ffffffff81a48025>] ?
