[Disk I/O error, Bus error]

얼마전에 중고로 서버를 구입했습니다. IBM xSeries 330 이었나 아마 그럴겁니다.
아무튼 뭐 그럭저럭 석달 정도를 사용을 했고, 몇일 전에 Kernel을 2.4.31로 올렸습니다.
SMP 머신이고요. 그래서 뭐 그것도 탈없이 사용했더랬는데, 어제 저녁 부터 이상 증상을 보이네요.
Linux는 RHEL 3.0 AS 입니다.

와 같이 Disk쪽에 에러가 있는 것처럼 나오네요. HW적인 문제라고 생각이 되는데요. 이유는 커널을 올려서 발생한 문제라면 벌써 나왔어도 나왔어야 하는 문제라는 생각이 드네요. 또 한가지 이유로는 중고를 구입하고 얼마 있지 않아 badblock을 체크 해 봤더니 badblock이 있는 걸로 나와서 SCSI-HDD를 새것으로 교체도 했거든요.

네 대를 구입했는데 이런 문제들이 계속 발생해서 저를 당화 스럽게 하네요.
혹 도움이 될만한 원인을 아시는 분께서 답변을 달아 주시면 상당히 감사 하겠습니다.
개발 서버로 이용하는 서버라 대략 난감하네요. --..--;;

그럼 미리 감사 드립니다.
