Hi All, I'm running OpenBSD on a box with GA-8S661FXM-775 Rev.1 motherboard, with the latest bios F4 (please see dmesg below). Previously I know that FreeBSD and Linux could not reboot this hardware, but I was hoping OpenBSD could, but it can't either. Linux can halt though, but others can't halt either. (I don't know what Windows would do.)
So this is not specific to OpenBSD, but I think misc@ may have some idea why these different OSs, and specifically OpenBSD, cannot reboot this hardware (i.e. when I enter 'reboot' at command line, the system stops after "rebooting..." line, and I have to press the reset button myself). The system otherwise does not have any problems that I know of. I tried different BIOS settings, removed NICs, etc. without success. I contacted Gigabyte too, no replies yet, and I'm not too hopeful. I googled too, but probably missed a relevant answer to my problem. What could be the reason? ACPI? PCI interrupt routing warning in dmesg? Hardware support? Any links? Any ideas please... Thanks, OpenBSD 3.9 (GENERIC) #617: Thu Mar 2 02:26:48 MST 2006 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Celeron(R) CPU 2.53GHz ("GenuineIntel" 686-class) 2.54 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,TM2,CNXT-ID real mem = 502833152 (491048K) avail mem = 451727360 (441140K) using 4278 buffers containing 25243648 bytes (24652K) of memory mainbus0 (root) bios0 at mainbus0: AT/286+(b3) BIOS, date 10/14/05, BIOS32 rev. 0 @ 0xfb4d0 apm0 at bios0: Power Management spec V1.2 apm0: AC on, battery charge unknown apm0: flags 70102 dobusy 1 doidle 1 pcibios0 at bios0: rev 2.1 @ 0xf0000/0xd914 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfd880/128 (6 entries) pcibios0: PCI Exclusive IRQs: 5 6 7 9 10 11 12 pcibios0: no compatible PCI ICU found: ICU vendor 0x1039 product 0x0964 pcibios0: Warning, unable to fix up PCI interrupt routing pcibios0: PCI bus #1 is the last bus bios0: ROM list: 0xc0000/0x8000 cpu0 at mainbus0 pci0 at mainbus0 bus 0: configuration mode 1 (no bios) pchb0 at pci0 dev 0 function 0 "SiS 661 PCI" rev 0x11 ppb0 at pci0 dev 1 function 0 "SiS 648FX AGP" rev 0x00 pci1 at ppb0 bus 1 vga1 at pci1 dev 0 function 0 "SiS 6330 VGA" rev 0x00: aperture at 0xe0000000, size 0x400000 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) pcib0 at pci0 dev 2 function 0 "SiS 964 ISA" rev 0x36 pciide0 at pci0 dev 2 function 5 "SiS 5513 EIDE" rev 0x01: 661: DMA, channel 0 configured to compatibility, channel 1 configured to compatibility pciide0: channel 0 ignored (disabled) atapiscsi0 at pciide0 channel 1 drive 0 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0: <HL-DT-ST, CD-ROM GCR-8522B, 1.03> SCSI0 5/cdrom removable cd0(pciide0:1:0): using PIO mode 3, DMA mode 1 sis0 at pci0 dev 4 function 0 "SiS 900 10/100BaseTX" rev 0x90: irq 10, address 00:14:85:cb:2c:85 icsphy0 at sis0 phy 1: ICS1893 10/100 PHY, rev. 1 pciide1 at pci0 dev 5 function 0 "SiS 180 SATA" rev 0x01: DMA pciide1: using irq 11 for native-PCI interrupt wd0 at pciide1 channel 0 drive 0: <SAMSUNG HD080HJ> wd0: 16-sector PIO, LBA48, 76318MB, 156299375 sectors wd0(pciide1:0:0): using PIO mode 4, Ultra-DMA mode 5 ne3 at pci0 dev 9 function 0 "Surecom Surecom NE-34" rev 0xd1: irq 11, address 00:00:21:c7:e8:a3 ne4 at pci0 dev 10 function 0 "Surecom Surecom NE-34" rev 0x01: irq 12, address 00:00:21:50:72:91 ne5 at pci0 dev 11 function 0 "Surecom Surecom NE-34" rev 0xd1: irq 10, address 00:00:21:c7:e8:40 isa0 at pcib0 isadma0 at isa0 pckbc0 at isa0 port 0x60/5 pckbd0 at pckbc0 (kbd slot) pckbc0: using irq 1 for kbd slot wskbd0 at pckbd0: console keyboard, using wsdisplay0 pcppi0 at isa0 port 0x61 midi0 at pcppi0: <PC speaker> spkr0 at pcppi0 it0 at isa0 port 0x290/8: IT87 npx0 at isa0 port 0xf0/16: using exception 16 pccom0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo pccom0: console pccom1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo biomask ebe5 netmask ffe5 ttymask ffe7 pctr: user-level cycle counter enabled dkcsum: wd0 matches BIOS drive 0x80 root on wd0a rootdev=0x0 rrootdev=0x300 rawdev=0x302 ne3: device timeout
