Hi, everyone, i have a problem with my IBM Thinkpad T42 2373 and OpenBSD 4.3 (stable and current), with 512mb of ram (default) works fine, when i add 1gb (kingston) the system works fine a few minutes, and then freeze without error o message.
Here is my dmesg: OpenBSD 4.3 (GENERIC) #698: Wed Mar 12 11:07:05 MDT 2008 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) M processor 1.60GHz ("GenuineIntel" 686-class) 1.60 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,TM,SBF,EST,TM2 real mem = 1609527296 (1534MB) avail mem = 1547259904 (1475MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 07/27/05, BIOS32 rev. 0 @ 0xfd750, SMBIOS rev. 2.33 @ 0xe0010 (61 entries) bios0: vendor IBM version "1RETDLWW (3.17 )" date 07/27/2005 bios0: IBM 2373RY1 apm0 at bios0: Power Management spec V1.2 apm0: battery life expectancy 97% apm0: AC on, battery charge high acpi at bios0 function 0x0 not configured pcibios0 at bios0: rev 2.1 @ 0xfd6e0/0x920 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfdea0/272 (15 entries) pcibios0: PCI Interrupt Router at 000:31:0 ("Intel 82371FB ISA" rev 0x00) pcibios0: PCI bus #6 is the last bus bios0: ROM list: 0xc0000/0x10000 0xd0000/0x1000 0xd1000/0x1000 0xdc000/0x4000! 0xe0000/0x10000 cpu0 at mainbus0 cpu0: Enhanced SpeedStep 1600 MHz (1340 mV): speeds: 1600, 1400, 1200, 1000, 800, 600 MHz pci0 at mainbus0 bus 0: configuration mode 1 (no bios) pchb0 at pci0 dev 0 function 0 "Intel 82855PM Host" rev 0x03 agp0 at pchb0: aperture at 0xd0000000, size 0x10000000 ppb0 at pci0 dev 1 function 0 "Intel 82855PM AGP" rev 0x03 pci1 at ppb0 bus 1 vga1 at pci1 dev 0 function 0 "ATI Radeon Mobility M7 LW" rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) uhci0 at pci0 dev 29 function 0 "Intel 82801DB USB" rev 0x01: irq 11 uhci1 at pci0 dev 29 function 1 "Intel 82801DB USB" rev 0x01: irq 11 uhci2 at pci0 dev 29 function 2 "Intel 82801DB USB" rev 0x01: irq 11 ehci0 at pci0 dev 29 function 7 "Intel 82801DB USB" rev 0x01: irq 11 usb0 at ehci0: USB revision 2.0 uhub0 at usb0 "Intel EHCI root hub" rev 2.00/1.00 addr 1 ppb1 at pci0 dev 30 function 0 "Intel 82801BAM Hub-to-PCI" rev 0x81 pci2 at ppb1 bus 2 cbb0 at pci2 dev 0 function 0 "TI PCI4520 CardBus" rev 0x01: irq 11 cbb1 at pci2 dev 0 function 1 "TI PCI4520 CardBus" rev 0x01: irq 11 em0 at pci2 dev 1 function 0 "Intel PRO/1000MT (82540EP)" rev 0x03: irq 11, address 00:11:25:d5:bb:e2 ipw0 at pci2 dev 2 function 0 "Intel PRO/Wireless 2100" rev 0x04: irq 11, address 00:13:e8:02:d6:9a cardslot0 at cbb0 slot 0 flags 0 cardbus0 at cardslot0: bus 3 device 0 cacheline 0x8, lattimer 0xb0 pcmcia0 at cardslot0 cardslot1 at cbb1 slot 1 flags 0 cardbus1 at cardslot1: bus 6 device 0 cacheline 0x8, lattimer 0xb0 pcmcia1 at cardslot1 ichpcib0 at pci0 dev 31 function 0 "Intel 82801DBM LPC" rev 0x01: 24-bit timer at 3579545Hz pciide0 at pci0 dev 31 function 1 "Intel 82801DBM IDE" rev 0x01: DMA, channel 0 configured to compatibility, channel 1 configured to co mpatibility wd0 at pciide0 channel 0 drive 0: <IC25N030ATCS04-0> wd0: 16-sector PIO, LBA, 28615MB, 58605120 sectors wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5 atapiscsi0 at pciide0 channel 1 drive 0 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0: <TOSHIBA, DVD-ROM SD-R9012, 1121> SCSI0 5/cdrom removable cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 2 ichiic0 at pci0 dev 31 function 3 "Intel 82801DB SMBus" rev 0x01: irq 11 iic0 at ichiic0 spdmem0 at iic0 addr 0x50: 512MB DDR SDRAM non-parity PC2700CL2.5 spdmem1 at iic0 addr 0x51: 1GB DDR SDRAM non-parity PC2700CL2.5 auich0 at pci0 dev 31 function 5 "Intel 82801DB AC97" rev 0x01: irq 11, ICH4 AC97 ac97: codec id 0ac97: codec features headphone, 20 bit DAC, No 3D Stereo audio0 at auich0 "Intel 82801DB Modem" rev 0x01 at pci0 dev 31 function 6 not configured usb1 at uhci0: USB revision 1.0 uhub1 at usb1 "Intel UHCI root hub" rev 1.00/1.00 addr 1 usb2 at uhci1: USB revision 1.0 uhub2 at usb2 "Intel UHCI root hub" rev 1.00/1.00 addr 1 usb3 at uhci2: USB revision 1.0 uhub3 at usb3 "Intel UHCI root hub" rev 1.00/1.00 addr 1 isa0 at ichpcib0 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 pms0 at pckbc0 (aux slot) pckbc0: using irq 12 for aux slot wsmouse0 at pms0 mux 0 pcppi0 at isa0 port 0x61 midi0 at pcppi0: <PC speaker> spkr0 at pcppi0 aps0 at isa0 port 0x1600/31 npx0 at isa0 port 0xf0/16: reported by CPUID; using exception 16 biomask effd netmask effd ttymask ffff mtrr: Pentium Pro MTRR support ugen0 at uhub3 port 2 "STMicroelectronics Biometric Coprocessor" rev 1.00/0.01 addr 2 softraid0 at root root on wd0a swap on wd0b dump on wd0b WARNING: / was not properly unmounted x41445374 (Analog Devices AD1981B) Any idea?
