linux報aic7xxx_abort returns 0x2002錯誤？（鬱悶問題未知）

aic7xxx_abort returns 0x2002

這個網站上也有很多朋友提出問題，不知道是不是核心錯誤？

（

用dmesg經常會發現伺服器報如下錯誤：
<<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>>
(scsi2:A:6:0): Device is disconnected, re-queuing SCB
(scsi2:A:6:0): Abort Message Sent
Recovery code sleeping
(scsi2:A:6:0): SCB 3 - Abort Completed.
Recovery SCB completes
Recovery code awake
aic7xxx_abort returns 0x2002
st0: Error with sense data: Current st0: sense key Hardware Error
Additional sense: Internal target failure

此裝置是磁帶機的，上網google了一下aic7xxx_abort returns 0x2002，發現很多人都有這個問題，但是好像都沒有解決辦法？
難道都是硬體有問題？有些懷疑呀！
