Looking at the result the machine under test seem to be low at entropy
we got 6 bytes with the first use of GRND_RANDOM instead of 256 and it
timeouted the second time we try to read some random bytes.

The problem here is that the machine does not have enough entropy
sources to produce random bytes and given that it wasn't able to
generate any in 15 minutes may as well be a kernel bug.
