This came about because I have been trying to expand some LVs on my system, which are based on a VG ontop of an MD mirror pair. It's an SMP box too if that means anything. device-mapper: table: 253:3: linear: dm-linear: Device lookup failed device-mapper: ioctl: error adding target to table device-mapper: table: 253:3: linear: dm-linear: Device lookup failed device-mapper: ioctl: error adding target to table device-mapper: table: 253:2: linear: dm-linear: Device lookup failed device-mapper: ioctl: error adding target to table BUG: unable to handle kernel paging request at virtual address 6f72702e printing eip: c018505b *pde = 00000000 Oops: 0000 [#1] 4K_STACKS SMP last sysfs file: /block/dm-2/removable Modules linked in: rfcomm l2cap bluetooth sbp2 i2c_piix4 ohci1394 evdev snd_ens1 371 snd_rawmidi snd_ac97_codec snd_ac97_bus i2c_core snd_pcm snd_timer snd sound core snd_page_alloc ieee1394 uhci_hcd ohci_hcd usb_storage CPU: 1 EIP: 0060:[] Not tainted VLI EFLAGS: 00010292 (2.6.18-rc5-mm1 #1) EIP is at bd_claim_by_disk+0x9b/0x1c0 eax: e6622ba0 ebx: 6f72702e ecx: c16decbc edx: 6f72702e esi: 00000000 edi: e4a11220 ebp: c16dec80 esp: c62e1ca4 ds: 007b es: 007b ss: 0068 Process lvextend (pid: 2926, ti=c62e1000 task=dccfa580 task.ti=c62e1000) Stack: c047cefa c16dec8c c16dec80 e3e31920 d1130e80 c16dec80 c035f9c8 fffffff4 e128d160 00900000 e3e31920 c036040c f0a5915c c042bf66 c62e1d50 c62e1d4c c0500f0c e128d160 f0a5915c f0a1b080 e128d0c0 00000000 00000001 c0500f0c Call Trace: [] open_dev+0x48/0x80 [] dm_get_device+0x20c/0x480 [] vsscanf+0x447/0x490 [] linear_ctr+0x99/0x110 [] dm_table_add_target+0x17d/0x2e0 [] table_load+0xba/0x1d0 [] ctl_ioctl+0x22d/0x2a0 [] n_tty_receive_buf+0x324/0x1070 [] table_load+0x0/0x1d0 [] do_ioctl+0x78/0x90 [] vfs_ioctl+0x5c/0x2b0 [] sys_ioctl+0x3d/0x70 [] syscall_call+0x7/0xb ======================= Code: 3c 8b 13 0f 18 02 90 8d 4d 3c 39 cb 0f 84 24 01 00 00 8b 47 0c 3b 43 0c 75 0f e9 ab 00 00 00 90 3b 43 0c 0f 84 a1 00 00 00 89 d3 <8b> 12 0f 18 02 90 39 cb 75 eb e8 d6 a9 0b 00 85 c0 89 47 0c 0f EIP: [] bd_claim_by_disk+0x9b/0x1c0 SS:ESP 0068:c62e1ca4
