Nikolay, thanks for the feedback, even if unfortunately it's negative...
I see that in both 8-STABLE (8.2-PRERELEASE now) and 9.0-CURRENT, both rebuilt 
no more than a week ago.
I've also tried rebuilding the kernel with:
   options         CAMDEBUG
   options         CAM_DEBUG_BUS=0
   options         CAM_DEBUG_TARGET=0
   options         CAM_DEBUG_LUN=0
   options         CAM_DEBUG_FLAGS=CAM_DEBUG_TRACE
(0 is the bus/target/lun of the marvell controller/attached hd)
and run a test computing md5 for about 60GB of files.
Obviously, as the debug options where active, it run successfully without any 
problems :)
Is there any other info I should provide or any other test that I can do?

Thanks
Barbara
