I think this is where your problem is.

With the recurring checksum issues you are seeing I would suspect that
something in your system is causing random data to be corruption. This
could be one of a thousand different things: a faulty RAM module, hard
drive cable, bad PSU, an over clocked or over heating CPU, bad PCI card
etc. Or it could be a software issue, such as a bad driver in the kernel
or X11. It can be really hard to identify the real cause but you could
try running memtest86+ or swapping around pieces of hardware.

I do not believe the files on the server are at fault. If they were then
I would expect to see many more complaints.

Until you can resolve the underlying data corruption issue then I don't
believe it is worth you trying different combinations of options with
osm2pgsql.
