Re: ioapic problem

["ºñ¿¡½ºµð" <bsdman@xxxxxxxxx>]

일전에(2003년 2월 18일 화요일) questions archive로 올렸던 저의 질문에 대한 자답입니다.

그때 올렸던 질문은 첨부화일을 참고하시기 바랍니다.

해당 SMP 문제에 대한 인텔 화이트박스 업체의 답변에 의하면(인텔의 공식적인
입장은 아닙니다.) SE7500CW2 보드의 SMP에 문제가 있는걸 인정했습니다.
(이 부분은 인텔 내부에서도 인정하는 사실이라고 합니다.)
인텔측에서는 아직 어떠한 해결책도 못내놓고 있는 상태이며, FreeBSD 를 이용하는
사용자들은 이 보드를 사용하지 않는것이 최선의 해결책으로 보입니다.
이 부분에 대해서는 freebsd.org 의 hackers archive에서도 몇몇 논의가 있었던 것으로 보입니다.
(http://docs.freebsd.org/mail/archive/2002/freebsd-hackers/20020915.freebsd-hackers.html)
이 보드에서 사용하고 있는 칩셋이 Intel® E7500 chipset 이며, 비슷한 다른 보드들
(SE7500WV2, SE7500BR2)은 SMP 문제가 없다고 합니다.
