Please see the following threads. http://marc.theaimsgroup.com/?l=linux-ide&m=112497821103098&w=2 http://marc.theaimsgroup.com/?l=linux-ide&m=112600646820285&w=2 > dd if=/dev/sda of=/dev/null can reproduct error, as can several > disk-intensive activities In the following mail, I've attached a patch which might alleviate errors during writes (as Alexander was reporting CRC errors with write commands), but it won't do any good if you're getting errors during reading. http://marc.theaimsgroup.com/?l=linux-ide&m=112602112819183&w=2 Carlos and Paul, do you guys know anything about this mainboard? Should we perform some special tweaking to get these boards work? I'll dig 3112/3114 document further but I'm not very sure what I should look for. Thanks. -- tejun
