We build our own BSD servers - always have. Pretty much always with the same hardware.
The latest system I've built sporadically spews forth these messages on the console with reckless abandon:
(da0:ahc0:0:0:0): Invalidating pack (da0:ahc0:0:0:0): Invalidating pack (da0:ahc0:0:0:0): Invalidating pack (da0:ahc0:0:0:0): Invalidating pack
Occasionally, I get interspersed with this things like:
(da0:ahc0:0:0:0): SCB 0x29 - timed out while idle, SEQADDR == 0x9 (da0:ahc0:0:0:0): Queuing a BDR SCB (da0:ahc0:0:0:0): no longer in timeout, status = 35b
The system is custom built as follows:
Asus P3B-F motherboard (both BIOS revisions 1004 and 1005) Adaptec 2940UW-Pro SCSI controller 1 Seagate 18Gb Baracuda drive 128Mb RAM Celeron 466MHz CPU (no overclocking!)
I have swapped out, individually, one at a time, each component of the SCSI subsystem - controller, cable, drive and terminator. I'm still getting the error message.
I pulled off the 4.0-RELEASE install that was on it and went back to 3.4-RELEASE; same problem.
After looking through the archives, I thought the 'Invalidating pack' message was a sure indicator of bad hardware/termination etc. Now I'm not so sure.
Anyone have some helpful suggestions?
Thanks,
Nick.

I think it might be a driver issue with freebsd. I have a very new system with 2 * 18G Seagate Cheetah drives connected to an Adaptec 29160 controller which was showing identical symptoms. I loaded OpenBSD to check if it was hardware or software (grasping at straws) and it has been running flat out for days since. (Looping make build, kind of like make world). Justin Gibbs did mention that he had some ideas, and some code which might be available after usenix, although I think this might be more specific to the 29160 set. There is no sign of any problem at all under OpenBSD, although the throughput seems to be less. (~26Mbytes/sec as opposed to ~34MBytes/Sec)
Just an extra data point, it might not be hardware at all.
Cheers Ian.
