Indeed ;-)

Here's my setup: Lombard with 6GB HD and 64MB RAM (just like yours
I guess); my probs started with USB support compiled in the kernel:
even if it does not lead to a total freeze so often (would say very
seldom indeed), I still get mouse freeze under X when heavy network
activity is being made (last time 5 mins ago getting a big attachment).
Some other times I get a kernel panic during the boot when initializing
the serial interfaces (no, I have NOT support for standard serial
but only MAC serial compiled into the kernel).
This is why I was thinking about some USB/serial code problem but I
agree we need some debug output to work on.

Using Debian 2.2 and XF86_FBDev with kernel 2.2.15pre20 from Paul's

Thinking about the debug way you suggest, it comes to my mind another
question not so related to the prob: is there a USB->serial converter
around ? Is there one of this devices supported by Linux ? On PPC ?
