VME-167 cards Also there are some C tasks. At some point (it varies, and doesn't happen every time) the best we can tell our SCSI disk is waiting on an interrupt and hanging. My Ada task is just sitting there taking minutes for individual i/o statements to complete. We have gotten the following statements on the screen (all three at the same time)- interrupt: ncr810: SCSI bus gross error interrupt: ncr810Intr: unrecoverable error - re-starting-SIOP (from one of our C tasks) (tScsiTask): ncr810InitEvent: invalid event type (99) --- We have checked stack sizes for blown stacks, no problems are indicated here. When the error occurs (some times on init, some times several minutes into recording) during a write we have seen a write error (number of bytes reported written does not match those sent) and we have seen a time out. One guess is something is 'jumping its bounds' and messing up memory where the device driver resides- but what? Any ideas? -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
