--- Comment #21 from Peter Much <pmc@citylink.dinoex.sub.org> ---
(In reply to Graham Perrin from comment #20)
This did not happen anymore recently, probably because of either
 * moving along with STABLE, or
 * having a (crude but somehow working) patch&workaround for the primary so=
urce
of troube, which is iwlwifi (as discussed in bug263613 and a bunch of other=
s.
That one appears to have some difficulty with separating duties between
linuxkpi and native code, and apparently produces strangely invalid objects=
 in
the kernel.) I'm now strictly unloading/reloading that module in any case of
doubt, and things are better.
