I've also ran stress-ng as in comment #1 (below) on 4 CPUs for 8 hours
on X/B/F.
No signs of issues: it finishes successfully and no weird messages in
the kernel logs.
$ sudo modprobe -a \
$(modinfo \
/lib/modules/$(uname -r)/kernel/crypto/*.ko \
/lib/modules/$(uname -r)/kernel/arch/*/crypto/*.ko \
| grep -ow 'crypto-.*')
$ ./stress-ng --version && ./stress-ng --af-alg 0 --timeout 8h 2>&1 | tee
../stress-ng.log.$(lsb_release -cs)-proposed
