I've been having occasional lock ups.
The screen will blank out like X has crashed and I see a tty login,

Can't get any input to machine with keyboard (like to switch to another
tty even), etc., so I reset or do a hard shutdown and reboot.

I dig into dmesg, and the only common thread I'm seeing is that it
happens when my Samsung Galaxy is plugged into the machine to recharge

Okay, I've looked in /var/log/kern.log
I think I found relevant stuff just before this latest lock-up.
I grabbed a whole bunch of it, mentioning CD-ROM, usb mass storage device and Samsung
(it's a phone, not an optical drive).

I can't help with the issue, I'm afraid, but I can shed a little light on this.

The phone contains an image of its "Driver CD" and presents this to the USB host as a CD-ROM, as well as presenting itself as a mass storage device.

The idea is that you can just plug the phone into your PC, it sees a CD drive with the drivers disc in and installs them (and, optionally, any additional software). Then it sees the device properly. This is usually for Windows users.
