From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tomas Carnecky Subject: Bug in btrfs_rename (kernel BUG at fs/btrfs/inode.c:5595!) Date: Wed, 13 Jan 2010 20:09:17 +0100 Message-ID: <4B4E1A5D.1070203@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8; format=flowed To: linux-btrfs@vger.kernel.org Return-path: List-ID: I was running v2.6.33-rc2-187-g08d869a and everything was ok. Today I decided to update the kernel (to v2.6.33-rc4) and a minute or two after logging into the gnome desktop this kernel bug appeared in dmesg. I then went back to the old kernel but the bug didn't disappear, not even after running btrfsck on the filesystem. tom ------------[ cut here ]------------ kernel BUG at fs/btrfs/inode.c:5595! invalid opcode: 0000 [#1] PREEMPT SMP last sysfs file: /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq CPU 1 Pid: 2462, comm: gconfd-2 Not tainted 2.6.33-rc2-00202-g63ebcc6 #12 776295G/776295G RIP: 0010:[] [] btrfs_rename+0x4c8/0x590 RSP: 0018:ffff88007a17dc78 EFLAGS: 00010282 RAX: 00000000ffffffef RBX: 0000000025fa67f8 RCX: ffff8800258b91b0 RDX: ffff880001d11c80 RSI: ffff8800258b9090 RDI: ffff8800258b9090 RBP: ffff88007a17dd38 R08: ffff880000000000 R09: 0000160000000000 R10: 0000000000000000 R11: 0000000000000000 R12: 000000004b4e1863 R13: ffff880071086060 R14: 0000000000000000 R15: ffff88007105b300 FS: 00007f468759e700(0000) GS:ffff880001d00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000006d9c90 CR3: 000000007b15e000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process gconfd-2 (pid: 2462, threadinfo ffff88007a17c000, task ffff88007c3e5840) Stack: 00000000000000fb ffff88007c3e5840 00000a897c3e5840 00000a8a00000a00 <0> 010000af7a17dcb8 ffff88000ba0e000 ffff880071086438 ffff88007219d000 <0> ffff88007219d000 ffff8800701d41a0 ffff8800288e2d80 ffff880071086060 Call Trace: [] vfs_rename+0x3da/0x420 [] sys_renameat+0x23e/0x270 [] ? _atomic_dec_and_lock+0x6b/0x90 [] ? mntput_no_expire+0x24/0xf0 [] ? sys_fchmodat+0x78/0x100 [] ? path_put+0x2c/0x40 [] sys_rename+0x16/0x20 [] system_call_fastpath+0x16/0x1b Code: 00 00 48 81 c7 b8 1a 00 00 e8 85 da d6 ff e9 56 fd ff ff 49 8b 77 10 48 8b bd 68 ff ff ff e8 80 fa ff ff 85 c0 0f 84 03 ff ff ff <0f> 0b eb fe 48 8b 75 80 48 8b bd 68 ff ff ff e8 24 15 01 00 e9 RIP [] btrfs_rename+0x4c8/0x590 RSP ---[ end trace 613e6e60575556d3 ]---
