Gerard,

In your last message you requested that I try running with tagged queueing
disabled, in an effort at diagnosing the chronic device timeouts on my
Alpha.

You guessed correctly! When I boot with "ncr53c8xx=tags:0", it works
reliably. I have been pounding on it for two days, and have yet to see a
timeout or error message. This is two days longer than it has ever stayed
up before <g>.

However, I note that it is slightly slower (perhaps 15% or so) than the
2.5f driver with queue depth of 4. Now that the problem area has been
isolated, is there any way that reliable tagged queueing can be achieved?

Thanks for your help to this point!

Steve
