Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org This is the message i get when trying to backup to a tape device. This backup procedure normally works fine, it just did this on a once off. The kernel is 2.6.8.1. Could this be related to a tape running out of capacity but not giving a nice error message? ------------[ cut here ]------------ kernel BUG at include/linux/dcache.h:276! invalid operand: 0000 [#1] SMP Modules linked in: st usb_storage nfsd exportfs snd_intel8x0 snd_ac97_codec snd_pcm snd_timer snd_page_alloc snd_mpu401_uart snd_rawmidi snd_seq_device snd soundcore ehci_hcd usbcore intel_agp agpgart evdev reiserfs initio i2c_i801 i2c_isa i2c_nforce2 it87 w83l785ts w83781d i2c_i810 i2c_algo_bit i2c_sensor i2c_core 8250 serial_core ac asus_acpi fan sk98lin CPU: 0 EIP: 0060:[] Not tainted EFLAGS: 00010246 (2.6.8.1) EIP is at d_alloc+0x149/0x194 eax: 00000000 ebx: ddadaef0 ecx: 00000000 edx: f750c0e0 esi: e8c8b020 edi: ddadaf6a ebp: f59f5eb4 esp: f59f5e1c ds: 007b es: 007b ss: 0068 Process tar (pid: 15544, threadinfo=f59f4000 task=f7dcb390) Stack: f7fd5580 000000d0 f59f5eb4 fffffff4 f52cd5f0 f52cd584 f750c0e0 c016162a f750c0e0 f59f5eb4 0000000e 00000000 f59f5f18 f7fc2580 f59f5eac c01618d3 f750c0e0 f59f5eb4 f59f5f18 f59f5eac e8c8b012 f52cd584 f59f5f18 c0161f5a Call Trace: [] real_lookup+0xaf/0xf0 [] do_lookup+0x96/0xa1 [] link_path_walk+0x67c/0xce9 [] opost+0x9a/0x1ac [] path_lookup+0x94/0x157 [] __user_walk+0x49/0x5e [] vfs_lstat+0x1c/0x58 [] tty_write+0x185/0x279 [] write_chan+0x0/0x21a [] sys_lstat64+0x1b/0x39 [] vfs_write+0xc9/0x119 [] sys_write+0x51/0x80 [] sysenter_past_esp+0x52/0x71 Code: 0f 0b 14 01 98 1b 36 c0 eb 9c 8d 43 2c 89 43 2c 89 43 30 eb ksymoops output: Warning: You did not tell me where to find symbol information.
