Hello, I'm setting up pf with altq support in my kernel on freebsd 9.0-Stable (soon to switch to the -RELEASE once it's available). The system is a quad-core Xeon E31220, running amd64. I've done a bit of googling and found various results. I know the freebsd handbook says ALTQ_NOPCC is required on SMP systems. My kern.timecounter.smp_tsc=1, which says the TSC is safe to use in SMP mode. Is it still required to use ALTQ_NOPCC on _ALL_ smp systems? Basically I'm just seeing very different answers with my own research, which is why I'm posting to this list. Thank you!
