4.8-STABLE Kernel Panic with dummynet options.
I first met this problem when our (60 students) internetgateway refused to
boot its new kernel, it was a 4.7-RELEASE. Then i loaded the old kernel and
went home to check if my 4.8-STABLE does likewise. And the answer was yes!
Both kernels were GENERIC + these options taken from the dummynet man pages:
options DUMMYNET
options NMBCLUSTERS
options HZ

status of autotuning freebsd for 9.2
Andre,
Are you going to have time to MFC things from -current for auto-tuning
-stable before 9.2?
I fear (maybe unnecessarily?) that we are about to ship yet another
release that can't do basic 10gigE when sufficient memory exists.
If you don't have time, then let me know and I'll see what I can do.
