I also see Oopses which seem to be sound related, although I did
not notice a correllation with the browser. The oopses below are from
2.6.17-rc1 with additional ipw2200 patches (first one), and from a clean
2.6.17 (second one). The -dirty suffix in the version numbers comes from
compiling with make-kpkg, not from actual changes to the source.
Please also note the slab corruptions mentioned below.
