I then used LVM2 tools to make the RAID array a physical volume, created a logical volume and formatted that volume with an XFS filesystem. Mounting the filesystem and copying over the 2.6 kernel source tree produces this OOPS (and is pretty reproducable): kernel BUG at fs/bio.c:177! invalid operand: 0000 [#1] CPU: 0 EIP: 0060:[] Not tainted EFLAGS: 00010246 EIP is at bio_put+0x2c/0x36 eax: 00000000 ebx: f6221080 ecx: c1182180 edx: edcbf780 esi: c577b998 edi: 00000002 ebp: edcbf780 esp: f78ffeb0 ds: 007b es: 007b ss: 0068 Process md0_raid5 (pid: 65, threadinfo=f78fe000 task=f7924080) Stack: c71e2640 c021d88d edcbf780 00000000 00000001 c1182180 00000009 0001000 edcbf780 00000000 00000000 00000000 c014e2fc edcbf780 00000000 00000000 f23a0ff0 f23a0ff0 edcbf7c0 c02ca51d edcbf780 00000000 00000000 00000000 Call Trace: [] bio_end_io_pagebuf+0x9a/0x138 [] bio_endio+0x59/0x7e [] clone_endio+0x82/0xb5 [] handle_stripe+0x8f2/0xec0 [] raid5d+0x71/0x105 [] md_thread+0xde/0x15c [] default_wake_function+0x0/0x12 [] md_thread+0x0/0x15c [] kernel_thread_helper+0x5/0xb Code: 0f 0b b1 00 bc 94 34 c0 eb d8 56 53 83 ec 08 8b 44 24 18 8b Hardware is a 2.6CGHz P4, 1G of RAM (4G highmem enabled), SMP kernel but no preemption.
