My DSL modem showed up yesterday, so I dropped it into my gateway box and fired it up. It immediately reported that it was unable to train; there was nothing to talk to on the other end of the phone line yet. Since my official install day is still a couple days out, that didn’t surprise me. Then this morning, I saw this in the logs:

Feb  9 08:19:22 guam kernel: wanpipe1: ADSL Link connected (Down 1792 kbps, Up 448 kbps)
Feb  9 08:19:30 guam kernel: wanpipe1: Link connected!
Feb  9 08:41:03 guam kernel: klogd 1.4.1#11, log source = /proc/kmsg started.

The gap between the second and third lines is the problem–the box went down, hard, right after the DSL line came up. On the other hand, it looks like I’m provisioned above 1.5384 on the ATM side. Assuming a 20% cell tax, this gives me a usable connection of around 1430 kbps down and 360 kbps up, which isn’t too bad. Now I just have to keep the thing from crashing. I’m rolling my ADSL drivers back from the beta version that I’d started with to the most recent release; hopefully that’ll be good enough to fix my problem.
