I am already running 3.3-STABLE (as of Thursday, I believe) because vinum improved quite a bit after 3.3-RELEASE. Joe> I thought a bus reset was supposed to deal with bus phase Joe> issues...?

I was looking at the system in preparation for putting another SCSI controller into it so I could get back the errors... and I removed the external terminator from the LVD chain to read it's label. Immediately, the screen started scrolling again with ahc messages --- This leads me to believe that everything is stuck waiting for the card to un-wedge. Now... I'd already hit CTRL-ALT-DEL to see if I could unwedge things... so the system didn't come back at that point, but I thought it was interesting. The following is my carefully typed sequence of messages from the console: (does not include messages after the terminator was removed). (da5:ahc0:0:9;0): SCB 0xd5 - time out in dataout phase, SEQADDR == 0x5e (da5:ahc0:0:9;0): BDR message in message buffer (da5:ahc0:0:9;0): SCB 0xd5 - time out in dataout phase, SEQADDR == 0x5d (da5:ahc0:0:9;0): no longer in timeout, status 34b ahc0: Issued Channel A Bus Reset. 4 SCBs aborted Dave. -- ============================================================================ |David Gilbert, Velocet Communications. | Two things can only be | |Mail: dgilbert@velocet.net | equal if and only if they | |http://www.velocet.net/~dgilbert | are precisely opposite. | =========================================================GLO================ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
