I built a system on 3.0-RELEASE, with a SCSI disk. The system works fine, except that occasionally, the da driver says: "Invalidating pack", and drops the disk offline and everything hangs. This is unfortunate. Reading through the code, there seemed to have been a bunch of changes made recently to the sys/cam/scsi/scsi_da.c code (among others) that deal with invalidating packs. Seeing this, I upgraded my /sys to 3.0-CURRENT last night, rebuilt the kernel and rebooted. This morning I woke to a crashed system and an "Invalidating pack" message on the console. Thus far, I've built 3 different SCSI systems from 3.0-RELEASE, and two of them have had this problem, with the third complaining about da related issues, but not dying. The third machine is a system that ran the 3.0-mumble-SNAP release from the CD for months without problem. So I don't think it is a hardware problem. What can I do to fix or workaround this problem? A quick answer would be appreciated, as the system which is crashing is one that I *really* need to be stable, and I'd rather not have to downrev to 2.2.x, which I'm going to need to do very soon, like today, if I can't get this issue stabilized.
