Start with a 3.6 kernel (which has lots of ENOSPC fixes in it). Try
mounting with -o ro, which won't allow you to modify anything but may
show you if the FS is at least mountable in that state (and will give
you the capability to copy the data elsewhere in extremis). If you're
lucky, that mount may then allow you to mount it again without the -o
ro.
