I have found additional information that may be useful regarding the hard hang I have been experiencing. Details were present in a previous message but here is a short summary. I have two of the exact same boxes (even same HD). They are i810 mobos with a Celeron 500 and 128MB ram and a 10GB IDE hard drive. One runs -stable and one runs -current. The -stable box has never crashed but the -current one used to hang every night (power light off, numlock stuck on). I swapped memory, drives, etc. -- same result: only the -current box would crash. I disabled ACPI and the -current box would stay up for a few days to a week before hanging. Now I removed the IDE hard drive and replaced it with a SCSI one and a Adaptec 2940 U2W HBA. Not only is the IO much faster but it has run for weeks without a hang. I would appreciate it if someone could help me look into this further. Are there known problems with this ATA chipset? It was running at UDMA33. * Swapping all hardware with the -stable box doesn't change anything * Disabling ACPI helps it run ~1 week before hanging * Swapping SCSI drive for IDE keeps it from hanging (at least for a few weeks) -Nate Old dmesg: (w/ ATA drive) Timecounter "i8254" frequency 1193182 Hz Timecounter "TSC" frequency 498486405 Hz CPU: Pentium II/Pentium II Xeon/Celeron (498.49-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x665 Stepping = 5 real memory = 133103616 (129984K bytes) avail memory = 124231680 (121320K bytes) pcib0: <Intel 82810 (i810 GMCH) Host To Hub bridge> at pcibus 0 on motherboard pci0: <PCI bus> on pcib0 atapci0: <Intel ICH0 ATA33 controller> port 0x1800-0x180f at device 31.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ad0: DMA limited to UDMA33, non-ATA66 cable or device ad0: 8297MB <Maxtor 90841U2> [16858/16/63] at ata0-master UDMA33 atapci0@pci0:31:1: class=0x010180 card=0x24118086 chip=0x24118086 rev=0x02 hdr=0x00 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
