it means that some eigenvalue calculation during 
a diagonalization failed. pwscf checks the error
status for calls to LAPACK and the error number
is the value of the INFO variable. to find out
more details, you have to search the source code
for 'CALL errore(...) ' statements. 

but of course this does not explain the 'real' 
problem. for that, however, you need to post your 
input file. there are many subtle (and some not so
subtle) ways to screw up an input. in some cases
it can also be important to know on what platform
you are running and what compiler/libraries you 
have used.

the espresso distribution comes with a large number
of instructive examples. perhaps you should have a
look at some of them and compare them to your system.
it is also a good idea to run some of them to verify,
that your executables work correctly.
