I had the same problem some month ago for some time, but I'm running -current on that box. At that time Stefan Esser did some modifications to ncr.c, I checked out the version before these changes but it didn't fix the problem. I suspect some other circumstances in the CAM stack to be the cause for it. "queue empty" is the default in a case statement. If someone can/want to track this down I'll help where I can. For some time now I havent got that error anymore, probably because I don't hit the HDD that hard anymore. -- Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
