Comment 1 for bug 1689367

arm32 syscall 384 is indeed getrandom, but QEMU implemented this in commit f894efd19917321 as of Feb 2016, which should be in 2.6 or later. I've just checked and the LTP test cases for getrandom all pass with qemu-arm-user and do invoke the getrandom syscall and don't provoke the warning from QEMU.

Can you check that the qemu-arm-static binary inside the chroot is really 2.9 and not an older version?
