Got this bug on Ubuntu 16.04 LTS server with 32-bit linux-image-4.4.0-92-generic.
My system has 32GB of RAM.
With USB 3.0 SanDisk Extreme Flash I got:
$ dd if=/dev/zero of=1G bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1,1 GB, 1,0 GiB) copied, 171,214 s, 6,3 MB/s
It's terrible slow!
Note: `sudo -w vm.highmem_is_dirtyable=1` helps on 32 bit system.
