During extended periods of heavy read activity (ie backups) the device and/or card will eventually hang, leaving the machine hung (there's a swap partition on that disk). The tape drive is on another SCSI controller, so it's not the problem. I have had varying success avoiding the problem by running backups from a vt while the machine is otherwise idle, but sometimes it hangs anyway. After the hang the 2940 access light is on solid, as is the light on the drive. I have upgraded to latest greatest drivers several times, since each has held the promise of more and smarter bus reset code, to no avail. I don't have another similar drive to experiment with, but on my AHA1542Cf this same drive had no problems. --Ben
