My hardware setup is: -Rather old P3 -5 HDDs (All Seagate, around 1 year old) --4 of those drives (all apart from the system drive) are connected to a Promise Ultra100 TX2 PCI controller card -vr network card My software setup is: -FreeBSD 5.4 -Custom kernel: --Workaround from i386/73706 applied --No APIC (Required for my vr network card to work) --Device hints disabling ACPI and APIC -The bare essentials running for a NFS/SMB server What happens, is that the machine will freeze (no HDD activity, doesn't respond to keyboard, doesn't respond to network, etc.), usually when there's a lot of HDD activity. I don't get any console error messages, helpful log messages, or anything - the machine just halts and I have to give it a hard reboot. It's been working fine for almost a week (sharing drives over NFS/ SMB), when this started happening (I didn't start anything special, in fact, I wasn't even using it). The last couple of times this has happened, has been during a fsck (during phase 1) of the drives after I'd noticed it had frozen. The next time I ran fsck, it completed fine, no errors. It doesn't seem to freeze on one particular drive - SMART status for the drives is fine, and I've run a few tests - all pass. The IDE cables are all 80-pin, nice, stiff, new ones as well. If this is a hardware problem (which it looks to be), I'd at least like to know where. Thanks, -Phil
