I was not paying attention to the cause of the oops, the system did not
crash. It is a dual p6 with a 3com 3c515 100bt adapter (driver from
Donald Beckers website (which still uses old pci - when will old pci
vanish?)). In general, 2.1.108ac2 is working *far* better than 2.1.104
that I was last testing.

Using `../System.map' to map addresses to symbols.
