This is the root cause for the failure. 0x2000 corresponds to:
#define IN_UNMOUNT 0x00002000 /* Backing fs was unmounted */
So, it's a potential kernel bug. Make sure that IN_UNMOUNT is properly
set at all levels between your copy of glibc and the kernel.

This is a symptom, not the root cause.

That's fine:
RETURN VALUES
If successful, the number of bytes actually read is returned. Upon read-
ing end-of-file, zero is returned. Otherwise, a -1 is returned and the
global variable errno is set to indicate the error.
