[other people's dmesg's snipped]

Hi, all,

I, too am now seeing an interrupt storm on irq 11 after upgrading to
april 5 (from ~jan 29).  The devices that are on irq 11 for me are
vgapci, uhci, ehci, bfe, fwohci, and a non-functional pcmcia modem
which attaches to sio.

A full dmesg may be found here (sorry it's not verbose, I can get one
if I need to), as well as pciconf -lv:
https://netfiles.uiuc.edu/kaduk/www/prolepsis/

My bfe network card seems to be working just fine, though I haven't
been stressing it too much.
