Detekcia iba jedneho jadra na Supermicro E3-1240 v3

[Marián Černý]

Ahoj,

snazim sa nainstalovat FreeBSD na novy Supermicro server a mam problem, ze je detekovane iba jedno jadro. Server je osadeny procesorom Intel Xeon E3-1240 v3. Tento procesor by mal mat 4 jadra.

V dmesg je toto:

Detekovane je jedno jadro s dvoma vlaknami (cpu0, cpu1).

Jedna sa o FreeBSD 9.2-RC4 amd64 s GENERIC jadrom. Na FreeBSD 9.1 sa to sprava rovnako.

Neviete niekto poradit, co mozem skusit urobit, aby boli detekovane vsetky jadra?
