I'm not sure the two are related. Fsync, lseek(), fadvise() will all fail if
the fd maps to a socket. The failure is harmless and the error return code
is ignored. The error to xend.log is overly noisy and needs cleaning up but
unfortunately the suspend/resume problems probably lie elsewhere. What
failure symptoms do you see?
