Hi,
The dmesg still complains about the "cant reuse leaf" as well as the other
PUC card now complains as well about "unable to activate interrupt in fast
mode - using normal mode"

I am using RELENG_5, so I am not sure if the HZ default has changed
yet. Not sure how much of this applies to RELENG_4 either where the
problem is particularly acute.
