Could you please elaborate a bit on what "rootkit" means in this
context?

We've been trying for the last several months to wean ourselves off the
ancient 2.4.19 kernel we have used in our fibre channel switch products
for many years (yes, a long overdue effort). This is one of many things
that worked with the old kernel but which now does not seem to work with
2.6.14. Whether it ever worked since we began this porting to 2.6 effort
is at this point an open question. We do make mods to open source kernel
space code like ethernet and flash drivers, but mucking with the core
networking stuff where this is implemented is something we like to
avoid, so its hard for me to see how we could have broke it here at
Brocade (but one never knows).

I tried searching for this at bugzilla.kernel.org and got no hits, but
then maybe the search criteria I used wasn't right.

Is nobody else seeing this?

Thanks,
