I'm using an experimental driver for the RAID 6 operations however as the error message below indicates that the bug is being caused elsewhere I wonder if this is a bug in the kernel. If not can anyone suggest a probable cause or method to help locate the cause of this bug? kernel BUG at mm/page_alloc.c:761! invalid operand: 0000 [#1] Modules linked in: raid6 xor radeon drm parport_pc lp parport autofs4 i2c_dev i2 c_core sunrpc ipt_REJECT ipt_state ip_conntrack iptable_filter ip_tables dm_mod video button battery ac ipv6 ohci_hcd hw_random sata_sil24 tg3 floppy ext3 jbd s ata_sil libata sd_mod scsi_mod CPU: 0 EIP: 0060:[] Not tainted VLI EFLAGS: 00010202 (2.6.15.2) EIP is at buffered_rmqueue+0xbd/0x1a3 eax: 00000001 ebx: c0319720 ecx: 00001000 edx: 00000001 esi: c0319720 edi: c0319740 ebp: eb9cfd24 esp: eb9cfcfc ds: 007b es: 007b ss: 0068 Process bonnie++ (pid: 4548, threadinfo=eb9cf000 task=ecd99030) Stack: 00001000 00000001 00000000 c1210000 00000246 000200d2 00000000 c03199ec 00000044 00000000 eb9cfd44 c0136367 00000003 00000000 000200d2 c03199e8 000200d2 eb9cfdb0 eb9cfd74 c01363d8 00000044 00000000 ecd99030 00000010 Call Trace: [] show_stack+0x76/0x7e [] show_registers+0xe8/0x150 [] die+0xbe/0x12f [] do_trap+0x7c/0x96 [] do_invalid_op+0x95/0x9c [] error_code+0x4f/0x54 [] get_page_from_freelist+0x74/0x8c [] __alloc_pages+0x59/0x271 [] generic_file_buffered_write+0x157/0x4b9 [] __generic_file_aio_write_nolock+0x3a6/0x3d1 [] __generic_file_write_nolock+0x74/0x8a [] generic_file_write+0x49/0xaf [] vfs_write+0xa9/0x14e [] sys_write+0x3b/0x60 [] sysenter_past_esp+0x54/0x75 Code: f0 e8 e3 fb ff ff 89 45 e4 8b 55 e8 89 d8 e8 26 ee 18 00 83 7d e4 00 0f 84 e9 00 00 00 8b 55 e4 89 f0 e8 5c f7 ff ff 85 c0 74 08 <0f> 0b f9 02 f5 88 2d c0 8b 96 38 01 00 00 bf 28 00 00 00 8d 82 Please CC me on any replies as I'm not subscribed to this list. thanks _______________________ Michael Gilroy Research Engineer A2E Limited Adaptive House Quarrywood Court Livingston EH54 6AX Scotland
