Doesn't sound like a filesystem problem --- if the hd remains on, it
sounds very much as if you've got something going wrong in the disk
stack, either in the ide driver or the disk itself giving up.  The
fact that it always happens when the modem is on also suggests that
this is not a filesystem problem.

Try reproducing it with a readable console enabled --- either run in
text console mode (no X), or set up a serial console and use another
machine to capture the output.  "ttywatch" is excellent for monitoring
serial consoles.
