USB stability problem
Greetings. I'm new both to this forum and to the powerpc architecture,
so please be patient ;)
I have an iMac 266 on which I am running Woody with the stock
2.4.18-newppc kernel. It's been outstanding in every way, until I
installed a printer yesterday. It's a DeskJet 1220C connected via USB.
In order for it to work, I needed to load the printer.o module (as
expected). When printing, half way through the print job the printing
stops and the printer abruptly begins outputting gibberish characters
and page feeds. Simultaneously, USB locks up, freezing keyboard and
mouse. The box is otherwise fine -- the screen refreshes and I can ssh
in. When I try to reboot via ssh, I get a hard lockup during shutdown
which requires a power-button hardware reset.
The logs show me this:

at the point where I did 'modprobe printer'. Then:

At the point where I USB locks up. I've never seen anything like this,
but I've never used USB HID before, as my i386 boxes have PS/2 stuff.
I assume I ought to log a bug, but to/with whom? I'm not a kernel
hacker, so I can't really contribute much on the kernel dev lists.
Is this a known issue, and is there a known workaround? I'd like to be
able to print :/
Thanks in advance for any wisdom listmembers might be able to send my
way!
