WARNING: at fs/btrfs/extent-tree.c:5695 btrfs_alloc_free_block+0x22c/0x370 [btrfs]()
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] [<ffffffff8104daeb>] ? warn_slowpath_common+0x7b/0xc0 May 30 23:25:17 localhost kernel: [17117.213625] [<ffffffffa01b650c>] ? btrfs_alloc_free_block+0x22c/0x370 [btrfs] May 30 23:25:17 localhost kernel: [17117.213636] [<ffffffff8139cc4c>] ? schedule+0x53c/0xd70 May 30 23:25:17 localhost kernel: [17117.213643] [<ffffffff8139ccbc>] ? schedule+0x5ac/0xd70 May 30 23:25:17 localhost kernel: [17117.213672] [<ffffffffa01e8a1f>] ? read_extent_buffer+0xcf/0x1e0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213698] [<ffffffffa01a2853>] ? __btrfs_cow_block+0x163/0x8d0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213727] [<ffffffffa01bfc69>] ? btrfs_buffer_uptodate+0x49/0x70 [btrfs] May 30 23:25:17 localhost kernel: [17117.213753] [<ffffffffa01a30d9>] ? btrfs_cow_block+0x119/0x2b0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213778] [<ffffffffa01a8b5c>] ? btrfs_search_slot+0x1dc/0x9b0 [btrfs] May 30 23:25:17 localhost kernel: [17117.213807] [<ffffffffa01bb493>] ? btrfs_lookup_file_extent+0x33/0x40 [btrfs] May 30 23:25:17 localhost kernel: [17117.213837] [<ffffffffa01d32b0>] ? btrfs_drop_extents+0xc0/0x960 [btrfs] May 30 23:25:17 localhost kernel: [17117.213847] [<ffffffff810096a5>] ? __switch_to+0xc5/0x300 May 30 23:25:17 localhost kernel: [17117.213854] [<ffffffff811f2861>] ? rb_insert_color+0x101/0x140 May 30 23:25:17 localhost kernel: [17117.213863] [<ffffffff8111ffdc>] ? kmem_cache_alloc+0x15c/0x180 May 30 23:25:17 localhost kernel: [17117.213894] [<ffffffffa01c93a9>] ? insert_reserved_file_extent.constprop.48+0x69/0x230 [btrfs] May 30 23:25:17 localhost kernel: [17117.213926] [<ffffffffa01ca272>] ? btrfs_finish_ordered_io+0x2f2/0x330 [btrfs] May 30 23:25:17 localhost kernel: [17117.213935] [<ffffffff8105d93a>] ? del_timer_sync+0x2a/0x50 May 30 23:25:17 localhost kernel: [17117.213965] [<ffffffffa01e4372>] ? end_bio_extent_writepage+0x122/0x160 [btrfs] May 30 23:25:17 localhost kernel: [17117.213994] [<ffffffffa01be2c9>] ? end_workqueue_fn+0x39/0x120 [btrfs] May 30 23:25:17 localhost kernel: [17117.214020] [<ffffffffa01f118e>] ? worker_loop+0x14e/0x4e0 [btrfs] May 30 23:25:17 localhost kernel: [17117.214047] [<ffffffffa01f1040>] ? worker_loop+0x0/0x4e0 [btrfs] May 30 23:25:17 localhost kernel: [17117.214054] [<ffffffff8106eb3e>] ? kthread+0x7e/0x90 May 30 23:25:17 localhost kernel: [17117.214061] [<ffffffff8100bc24>] ? kernel_thread_helper+0x4/0x10 May 30 23:25:17 localhost kernel: [17117.214068] [<ffffffff8106eac0>] ? kthread+0x0/0x90 May 30 23:25:17 localhost kernel: [17117.214075] [<ffffffff8100bc20>] ? 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 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It''s the beginning of the logging. I''m sorry to say so, but I''m absolutely unable to boot into 3.0rc1 I used a complete with luks encrypted btrfs partition, there is only another /boot partition with ext4 - and this system is running since march 2010. On other kernels (2.6.38 or 2.6.39) - the logging starts much more early - but like I said - the load was unbelieveable high the whole time, the hard disks reached maximum temperature (so it was very hard to lay the hands on the computer) - and my only explanation are these entries.
