Hi!
I have a brand new Dell Inspiron 9100 laptop with a broadcom integrated
NIC.
I get a panic with 5.3-SNAP, 5.4-PRE and 6.0-SNAP due to a storm
interrupt as soon as I assign an IP address to it (ifconfig or
dhclient).
The storm interrupt is reported on "irq18: bfe0 uhci2".
I have manage to use this laptop with NDISulator but I cannot boot
LiveCD such as FreesBie.
Here are many information I think might be useful, feel free to ask me
more. I can manage to provide a remote access to this laptop (with
NDISulator, so not sure if usable to debug if_bfe ;) )

Not sure if it is related with but I have (mostly) random freeze of the
system while browsing files with firefox/mozilla or other file browsers:
but i'll report them lately.
Thanks for your help.
Phil.
