[Bug 605436] Re: kpartx fails to map partitions (device-mapper: resume ioctl failed: Invalid argument)

[Malte S. Stretz]

Looks like this is still an issue in Precise (see below). You can find
the most recent version of that image at
http://m0n0.ch/wall/downloads.php (get the generic-pc-1.33.img). I can't
judge about Quantal.

  dmesg says:

  It seems like this is debian bug 586104 and fixed in newer versions of
  multipath-tools.
