Subject: adaptec aic7xxx bug
hi ,
I have a nfs server running sarge (Dual Xeon 2.4GHz , 6 GB RAM) .
I am running 2.6.11.6 and 2.6.11.8 kernels. Under load the adpatec card which I
use to connect my external RAID flakes . I have got the vendor to replace
everything on the system from mainboard, external raid chassis to cables.
cat /proc/scsi/aic7xxx/1
Adaptec AIC7xxx driver version: 6.2.36
Adaptec 3960D Ultra160 SCSI adapter
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
