[Pkg-cryptsetup-devel] Bug#402417: instructions for the solution

[Leonard Norrgard]

After this package has been upgraded, just reinstall the kernel that
previously couldn't boot.  This causes the initrd image to be recreated
correctly and when the computer is rebooted everything will work.

Adding the original error message here, so people who are searching
for the fix can find it:

----
device-mapper: table: 253:4: crypt: Error allocating crypto tfm
device-mapper: ioctl: error adding target to table
device-mapper: ioctl: device doesn't appear to be in the dev hash table.
Failed to setup dm-crypt key mapping.
...
Failed to read from key storage
