Bug#586104: fails to map extended partitions

[martin f krafft]

Package: kpartx
Version: 0.4.8+git0.761c66f-8
Severity: normal

I have three extended partitions on /dev/loop0:

  % sudo sfdisk -d /dev/loop0
  Warning: extended partition does not start at a cylinder boundary.
  DOS and Linux will interpret the contents differently.
  # partition table of /dev/loop0
  unit: sectors

  /dev/loop0p1 : start=       16, size=  7812464, Id= c
  /dev/loop0p2 : start=  7812480, size=  3906240, Id=83, bootable
  /dev/loop0p3 : start= 11718720, size=  3944320, Id= 5
  /dev/loop0p4 : start=        0, size=        0, Id= 0
  /dev/loop0p5 : start= 11718736, size=   976624, Id=83
  /dev/loop0p6 : start= 12695376, size=   195184, Id=83
  /dev/loop0p7 : start= 12890576, size=  2772464, Id=83

kpartx cannot handle that it seems:

% sudo kpartx -av /dev/loop0
add map loop0p1 (253:16): 0 7812464 linear /dev/loop0 16
add map loop0p2 (253:17): 0 3906240 linear /dev/loop0 7812480
add map loop0p3 (253:18): 0 3944320 linear /dev/loop0 11718720
device-mapper: resume ioctl failed: Invalid argument
add map loop0p5 : 0 976624 linear 253:18 11718736
device-mapper: resume ioctl failed: Invalid argument
add map loop0p6 : 0 195184 linear 253:18 12695376
device-mapper: resume ioctl failed: Invalid argument
add map loop0p7 : 0 2772464 linear 253:18 12890576

% ls /dev/mapper/loop0p*
/dev/mapper/loop0p1  /dev/mapper/loop0p2  /dev/mapper/loop0p3
