Well, this is interesting. I disabled HTT in the BIOS and rebooted with a SMP kernel. As expected, there is only one CPU available after boot. However, FreeBSD still detects that the CPU is HTT-capable and prints the following in dmesg output: CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2793.01-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf33 Stepping = 3 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR, SSE,SSE2,SS,HTT,TM,PBE> Hyperthreading: 2 logical CPUs If my sig11 issue doesn't recur now that HTT is off I'll go back to a non-SMP kernel and confirm there are no issues there too.
