Bug#393301: lvcreate: page allocation failure. order:2, mode:0xd0

[Micha Lenk]

Hi again,

in userspace lvcreate did output following lines when trying to create 
the snapshot:

   device-mapper ioctl cmd 9 failed: Cannot allocate memory
   Couldn't load device 'mainvol-var_snap'.
   Problem reactivating origin var

 From munin's memory watch I can't see any hint that there was a shotage 
of memory before the oops:
