As I have similar problems, here my report: I have an Adaptec 29160 and tried to connect an EasyRaid II U3 to it and get the same errors as above (I can send detailed output with verbose in a few days). I tried kernel version 2.4.2-2 from Redhat, 2.4.7, 2.4.9 and 2.4.10 from kernel.org. - always the same result. Now the funny parts: if I leave the adapter-config to 160MB/s everything works, except for many error-messages. If I reduce the speed in the Controller-Setup to something lower (tried 80,40,20,10) there are much more error-messages and the system hangs after the scsi-scan shping endless SCSI-Errors. If I disable LVD by using an old non-LVD-TErminator the system speeds down to 40MB/s and everything works fine (I'm using the system in this mode now). But it is not a general U160-Problem as I have a second system with 5 IBM-U160-SCSI-Disks connected to an identical controller that is working fine at 160MB/s I tried several cables (the one that worked on the IBM-disks) round and flat ones and terminators - everything sold for U160, and both controllers. I would appreciate any help, because disabling LVD is not the best way, because I have to connect a second raid soon - each transfering about 40MB/s on its own. Regards, Bernhard B.
