Hi, I've been consistently experiencing a problem with one of our FreeBSD boxes (the only one running a SCSI subsystem with an embedded Adaptec Ultra2 SCSI controller): ahc0: <Adaptec aic7896/97 Ultra2 SCSI adapter> port 0xe400-0xe4ff mem 0xfebfe000-0xfebfefff irq 16 at device 11.0 on pci0 ahc1: <Adaptec aic7896/97 Ultra2 SCSI adapter> port 0xe800-0xe8ff mem 0xfebff000-0xfebfffff irq 16 at device 11.1 on pci0 About once a week, the following message is logged in the system's messages file, and the box stops responding altogether: (da0:ahc0:0:0:0): Invalidating pack I started experiencing this problem after migrating to 4.1. I then upgraded to 4.1.1 and later to 4.2-STABLE hoping it was related to minor problems with the ahc driver that might have been fixed in the later releases, but unfortunately the problem persists. Is there anyone out there experiencing the same problem? Anyone that can shed some light on what's happening here? As I mentioned, the problem manifests itself mostly after the box has been up for a few days -- no real "activity" to speak of, the machine is a router/firewall server.
