Re: power button halt vs reboot(8) and halt(8)
hmm, on Fri, Jul 13, 2012 at 11:58:40PM +0200, frantisek holop said that the reason i ask is, that fairly often, reboot(8) and halt(8) hangs (X disappears, but there is only black screen, and the console never appears, no syncing disks message), but pressing the power button turns off the machine without fail every time. another one of those mysteries.. i would like to add a minor correction, the power button can also fail as i have experienced later. but its success rate seems to be higher. as suspend does not work on this netbook at the moment, i will be able to keep statistics about the failures.. -f -- a day without sunshine is like night.

I can confirm this happens on my Thinkpad T400, too. I did not yet dig further into this, so I provide at least some system info; dmesg, pcidump, Xorg.0.log. $ dmesg I have seen this also. But not only when shutting down. Lately I start X from the command line and sometimes it indeed hangs when closing X, but it is no hard lock. Pressing ctrl-alt-backspace did the trick to continue the shutdown. Switching to an other console kept working. When I was using kdm and it happens, I sometimes started reboot in another console. But... I don't know if it did the trick. I do can remember that there were two shutdown process at work, so I think it did. I have to say that it was worse with the rtrheads transition, but lately I haven't seen it that often. But, this laptop almost never shuts down. I only restart kde when konqueror is giving trouble. But I suspect that something is choking on the X processes. I don't know all the technical details, but I would think that X first shuts down his processes and then calls the shutdown program. So shutdown wouldn't be involved with killing X processes. I can imagine that the power button uses something which act the same like kill -KILL and thus capable off killing X. hope this helps. gr Renzo ps I'm running a current build from 4-26-12
power button halt vs reboot(8) and halt(8)
hi there, how different is the code path between reboot(8), halt(8) and when i press the power button? the reason i ask is, that fairly often, reboot(8) and halt(8) hangs (X disappears, but there is only black screen, and the console never appears, no syncing disks message), but pressing the power button turns off the machine without fail every time. another one of those mysteries.. happened on multiple notebooks for me, but here is the dmesg for the one i use daily nowadays. -f OpenBSD 5.2-beta (GENERIC.MP) #308: Thu Jul 12 13:04:08 MDT 2012 t...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP cpu0: Intel(R) Atom(TM) CPU N570 @ 1.66GHz (GenuineIntel 686-class) 1.67 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,NXE,LONG,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,LAHF real mem = 1061818368 (1012MB) avail mem = 1033588736 (985MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 03/31/10, SMBIOS rev. 2.6 @ 0xeb0f0 (53 entries) bios0: vendor LENOVO version 50CN12WW date 04/22/2011 bios0: LENOVO 20109 acpi0 at bios0: rev 3 acpi0: sleep states S0 S1 S3 S4 S5 acpi0: tables DSDT FACP APIC MCFG SLIC HPET acpi0: wakeup devices P0P8(S4) PS2K(S3) PS2M(S3) EUSB(S3) P0PA(S4) P0PB(S4) P0PC(S4) P0P9(S3) USB0(S3) USB1(S3) USB2(S3) USB3(S3) PWRB(S3) SLPB(S3) acpitimer0 at acpi0: 3579545 Hz, 24 bits acpimadt0 at acpi0 addr 0xfee0: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: apic clock running at 166MHz cpu1 at mainbus0: apid 1 (application processor) cpu1: Intel(R) Atom(TM) CPU N570 @ 1.66GHz (GenuineIntel 686-class) 1.67 GHz cpu1: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,NXE,LONG,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,LAHF cpu2 at mainbus0: apid 2 (application processor) cpu2: Intel(R) Atom(TM) CPU N570 @ 1.66GHz (GenuineIntel 686-class) 1.67 GHz cpu2: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,NXE,LONG,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,LAHF cpu3 at mainbus0: apid 3 (application processor) cpu3: Intel(R) Atom(TM) CPU N570 @ 1.66GHz (GenuineIntel 686-class) 1.67 GHz cpu3: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,NXE,LONG,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,LAHF ioapic0 at mainbus0: apid 4 pa 0xfec0, version 20, 24 pins acpimcfg0 at acpi0 addr 0xf000, bus 0-63 acpihpet0 at acpi0: 14318179 Hz acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 3 (P0P8) acpiprt2 at acpi0: bus 2 (P0PA) acpiprt3 at acpi0: bus -1 (P0PB) acpiprt4 at acpi0: bus -1 (P0PC) acpiprt5 at acpi0: bus 1 (P0P9) acpiec0 at acpi0 acpicpu0 at acpi0:, C3, C2, C1, PSS acpicpu1 at acpi0:, C3, C2, C1, PSS acpicpu2 at acpi0:, C3, C2, C1, PSS acpicpu3 at acpi0:, C3, C2, C1, PSS acpibtn0 at acpi0: PWRB acpibtn1 at acpi0: SLPB acpibtn2 at acpi0: LID_ acpiac0 at acpi0: AC unit online acpibat0 at acpi0: BAT1 model LNV-L10C6Y12 serial 004706 type LiIon oem CPT-ES3 acpivideo0 at acpi0: GFX0 acpivout0 at acpivideo0: DD02 bios0: ROM list: 0xc/0xda00! 0xce000/0x1000 cpu0: Enhanced SpeedStep 1663 MHz: speeds: 1667, 1334, 1000 MHz pci0 at mainbus0 bus 0: configuration mode 1 (bios) pchb0 at pci0 dev 0 function 0 Intel Pineview DMI rev 0x02 vga1 at pci0 dev 2 function 0 Intel Pineview Video rev 0x02 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) intagp0 at vga1 agp0 at intagp0: aperture at 0xd000, size 0x1000 inteldrm0 at vga1: apic 4 int 16 drm0 at inteldrm0 Intel Pineview Video rev 0x02 at pci0 dev 2 function 1 not configured azalia0 at pci0 dev 27 function 0 Intel 82801GB HD Audio rev 0x02: msi azalia0: codecs: Realtek ALC269 audio0 at azalia0 ppb0 at pci0 dev 28 function 0 Intel 82801GB PCIE rev 0x02: apic 4 int 16 pci1 at ppb0 bus 1 re0 at pci1 dev 0 function 0 Realtek 8101E rev 0x05: RTL8105E (0x4080), apic 4 int 16, address 50:af:73:14:da:b5 ukphy0 at re0 phy 7: Generic IEEE 802.3u media interface, rev. 2: OUI 0x000732, model 0x0008 ppb1 at pci0 dev 28 function 1 Intel 82801GB PCIE rev 0x02: apic 4 int 17 pci2 at ppb1 bus 2 Realtek 8188CE rev 0x01 at pci2 dev 0 function 0 not configured uhci0 at pci0 dev 29 function 0 Intel 82801GB USB rev 0x02: apic 4 int 23 uhci1 at pci0 dev 29 function 1 Intel 82801GB USB rev 0x02: apic 4 int 19 uhci2 at pci0 dev 29 function 2 Intel 82801GB USB rev 0x02: apic 4 int 18 uhci3 at pci0 dev 29 function 3 Intel 82801GB USB rev 0x02: apic 4 int 16 ehci0 at pci0 dev 29 function 7 Intel 82801GB USB rev 0x02: apic 4 int 23 usb0 at ehci0: USB revision 2.0 uhub0 at usb0 Intel EHCI root hub rev 2.00/1.00 addr 1 ppb2 at pci0 dev 30 function 0 Intel 82801BAM Hub-to-PCI rev 0xe2 pci3 at ppb2 bus 3 pcib0 at
