Hi,
really need some advice on this since it's driving me crazy by now since I
cannot determine the problem:
Jun 25 20:27:50 daemon /kernel: SEQADDR == 0x110
Jun 25 20:28:18 daemon /kernel: Unexpected busfree. LASTPHASE == 0x40
Jun 25 20:28:19 daemon /kernel: SEQADDR == 0x10f
Jun 25 20:28:47 daemon /kernel: Unexpected busfree. LASTPHASE == 0x40
Jun 25 20:28:47 daemon /kernel: SEQADDR == 0x110
Jun 25 20:29:15 daemon /kernel: Unexpected busfree. LASTPHASE == 0x40
Jun 25 20:29:15 daemon /kernel: SEQADDR == 0x10f
Jun 25 20:29:44 daemon /kernel: Unexpected busfree. LASTPHASE == 0x40
Jun 25 20:29:44 daemon /kernel: SEQADDR == 0x10f
Jun 25 20:30:12 daemon /kernel: Unexpected busfree. LASTPHASE == 0x40
Jun 25 20:30:12 daemon /kernel: SEQADDR == 0x110
Jun 25 20:30:40 daemon /kernel: Unexpected busfree. LASTPHASE == 0x40
Jun 25 20:30:40 daemon /kernel: SEQADDR == 0x10f
That's what I get when I/O intense stuff happens on one of my HD's. Funny
thing is it's always this particular HD. Not one of the others.
My current setup consists of:
ahc0: <Adaptec 2940 Ultra SCSI adapter> irq 11 at device 17.0 on pci0
ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs

This is on a CURRENT system, cvsupped daily and made world (almost) daily.
I also had a 2940U2W in there which gave the same problems.
It's currently laid out like this:
da2-----ahc----da1---da0---cd0---active-terminator
I have termination of on all devices except da2. Termination of the ahc is
set to high on/low off or even automatic.
The ahc/da2 cable is a 68 pins cable
the other cable is a 50 pins one.
Do you guys reckon I need to buy an active terminator for my 68 pins cable
as well or buy a new cable?
If any more information is needed I am happy to give it... (like cable
langth and such)
Thank you very much in advance,
