From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sascha Biermanns Subject: WARNING: at fs/btrfs/extent-tree.c:5695 btrfs_alloc_free_block+0x22c/0x370 [btrfs]() Date: Tue, 31 May 2011 10:12:58 +0200 Message-ID: <4DE4A30A.9010207@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-15 To: linux-btrfs@vger.kernel.org Return-path: List-ID: Yesterday, I compiled the new kernel 3.0rc1 from git, but I never successed to go over the point: "Removing old temporary files". Pressing control-c let me boot on, but the pc was the complete time on very high load. It took me minutes, just to reach the tty login - and again minutes after login in, that I had my shell and a prompt to enter something. The load was at that time beyond 10. Now in my /var/log/messages, I found the following warning - and because it happens when "removing" temporary/old files, that might be why the computer has so much trouble: May 30 23:25:17 localhost kernel: [17117.213589] Call Trace: May 30 23:25:17 localhost kernel: [17117.213598] [] ? warn_slowpath_common+0x7b/0xc0 May 30 23:25:17 localhost kernel: [17117.213625] [] ? btrfs_alloc_free_block+0x22c/0x370 [btrfs] May 30 23:25:17 localhost kernel: [17117.213636] [] ? schedule+0x53c/0xd70 May 30 23:25:17 localhost kernel: [17117.213643] [] ? schedule+0x5ac/0xd70 May 30 23:25:17 localhost kernel: [17117.213672] [] ? read_extent_buffer+0xcf/0x1e0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213698] [] ? __btrfs_cow_block+0x163/0x8d0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213727] [] ? btrfs_buffer_uptodate+0x49/0x70 [btrfs] May 30 23:25:17 localhost kernel: [17117.213753] [] ? btrfs_cow_block+0x119/0x2b0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213778] [] ? btrfs_search_slot+0x1dc/0x9b0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213807] [] ? btrfs_lookup_file_extent+0x33/0x40 [btrfs] May 30 23:25:17 localhost kernel: [17117.213837] [] ? btrfs_drop_extents+0xc0/0x960 [btrfs] May 30 23:25:17 localhost kernel: [17117.213847] [] ? __switch_to+0xc5/0x300 May 30 23:25:17 localhost kernel: [17117.213854] [] ? rb_insert_color+0x101/0x140 May 30 23:25:17 localhost kernel: [17117.213863] [] ? kmem_cache_alloc+0x15c/0x180 May 30 23:25:17 localhost kernel: [17117.213894] [] ? insert_reserved_file_extent.constprop.48+0x69/0x230 [btrfs] May 30 23:25:17 localhost kernel: [17117.213926] [] ? btrfs_finish_ordered_io+0x2f2/0x330 [btrfs] May 30 23:25:17 localhost kernel: [17117.213935] [] ? del_timer_sync+0x2a/0x50 May 30 23:25:17 localhost kernel: [17117.213965] [] ? end_bio_extent_writepage+0x122/0x160 [btrfs] May 30 23:25:17 localhost kernel: [17117.213994] [] ? end_workqueue_fn+0x39/0x120 [btrfs] May 30 23:25:17 localhost kernel: [17117.214020] [] ? worker_loop+0x14e/0x4e0 [btrfs] May 30 23:25:17 localhost kernel: [17117.214047] [] ? worker_loop+0x0/0x4e0 [btrfs] May 30 23:25:17 localhost kernel: [17117.214054] [] ? kthread+0x7e/0x90 May 30 23:25:17 localhost kernel: [17117.214061] [] ? kernel_thread_helper+0x4/0x10 May 30 23:25:17 localhost kernel: [17117.214068] [] ? kthread+0x0/0x90 May 30 23:25:17 localhost kernel: [17117.214075] [] ? kernel_thread_helper+0x0/0x10 May 30 23:25:17 localhost kernel: [17117.214080] ---[ end trace 6e2121230335769a ]--- May 30 23:25:17 localhost kernel: [17117.214109] ------------[ cut here ]------------ May 30 23:25:17 localhost kernel: [17117.214135] WARNING: at fs/btrfs/extent-tree.c:5695 btrfs_alloc_free_block+0x22c/0x370 [btrfs]() May 30 23:25:17 localhost kernel: [17117.214140] Hardware name: Presario CQ56 Notebook PC
