Hi, I have a similar problem with another controller - AOC-2020SA (with "Adaptec" printer on the board), which is a Zero-Channel RAID controller working with the onboard Marvel MV88SX6041 SATA controller.
Tested with Debian kernels: 2.6.12-1-amd64-k8-smp ([EMAIL PROTECTED]) (gcc version 4.0.2 (Debian 4.0.1-9)) #1 SMP Wed Sep 28 02:57:49 CEST 2005 2.6.8-11-amd64-k8-smp ([EMAIL PROTECTED]) (gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-13)) #1 SMP Wed Jun 1 00:01:27 CEST 2005 The symptom is very strange. First, if any of ide_generic, am74xx drivers is loaded (to be able to access the DVD via the embedded AMD74xx IDE controller) aacraid hangs on high load with messages: Oct 4 16:20:23 kovo kernel: aacraid: Host adapter reset request. SCSI hang ? Oct 4 16:20:23 kovo kernel: aacraid: Host adapter appears dead Oct 4 16:20:23 kovo kernel: scsi: Device offlined - not ready after error recovery: host 0 channel 0 id 0 lun 0 After booting without loading any IDE module, the array seems stable, but gives wrong data. I copied a 7G file on the array and ran md5sum for it several times and got different (and wrong) result each time. If I copy a 1.5G file via scp and immediatelly after the copy chech its md5 sum - it is correct, but this is becuase the system has 2G of memory and 1.5G file can easyly fit in the cache. If after siccessfully md5sum-chech of this 1.5G file I try (unsuccessfuly) to check the 7G file, then the 1.5G file fails the check again (I suppose, because it is removed from cache and read from the array again). Here's sample calculating small/big files sha1sum three times $ for i in 1 2 3 ; do echo "----------"; sha1sum big.gz; sha1sum big; done ---------- 4064d7a21eddcc00518d9a3b35c9ec9b9731a80f big.gz 06dd17ae3028e6f78d75502dbf858fe65de0f880 big ---------- f839eae0cf46c80debfd5f4e437b6aaa373d2278 big.gz c894a8485d62310dd1c909e425ae501eaa9c3836 big ---------- 9ecd7bd6ded1d9d486a2d0cbdb3032bff5d33a04 big.gz e727625c7535a2886e4be9806e7e4e9a5d85c9a1 big I hope this rings some bells. dam P.S.
