Subject: Re: rtl8180 freeze some i386 systems

I added linux-wireless to the CC list.

If you're on the terminal is anything printed to the screen when the
system hangs?  echo 7 7 7 7 > /proc/sys/kernel/printk first to get more
messages.

If you create a bugzilla entry then you can take a digital photo of
the messages and attach it to your bug report.  (Although bugzilla is
crapping out today so you probably can't do that actually).
