I was planning on doing a back-up of the #Ceph cluster today in preparation of migrating it to a later release… but of course, I've misplaced the PSU for my external 4TB back-up drive.

I noticed it was getting pretty tight on space too, and given it's now 5 years old, figured it was time for a new one. I've got a 6TB one coming.

In the meantime, I had another crack at the Ericsson F5521GW 3G module in the Toughpad.

If I boot with init=/bin/bash on the kernel command line, then modprobe cdc-acm, I see 3 ACM devices appear, and I can use `screen` with them.

I managed to remove the old PIN code on the SIM card I have in there but couldn't get the GPS going, most I got out of it was a "Operation not allowed" error.

Doing this in early init seems to be enough to convince the module to stay enumerated. Something though, tells it to go bugger off early in the boot sequence unless I talk to it first.

A bit of a nuisance to be honest… but I'm somewhat closer.
