I was just detailing my experience to correlate with Amancio's report. I have tried several driver revisions (because I was way downrev on FreeBSD when I got the card) and the results are largely unchanged over several driver versions. I don't know if it's a problem with the drive, the card, the driver, or the OS's use of the driver. I would pursue it, but I have no device driver experience. I'm open to suggestions, requests for experiments and beta testing. > I do hope that you will at least try the revision > that was just committed to the tree. I will do that when I get a chance (my birthday is tommorow, so I'll be busy). My repeat-by is just 'dump ...', which usually hangs a few minutes after it starts dumping regular files. Would any ouput (trace, crash dump, etc) be useful? Does anyone have a similar (SCSI2 ~2G drive) on a 2940 that has had similar experiences? --Ben
