Summary ======= I have an IBM/Lenove Thinkpad T42 (model 2373-9XU, dmesg below) running 4.4-stable. apm & speedstep work fine, but when I try to suspend-to-RAM (either with Fn-F4 or with /usr/sbin/zzz): * About half of the time it works perfectly: the "moon" light under the display blinks for a second or two, then there's a beep and the power light goes out, the moon light stays on continuously, the disk and fan stop, and the system is in suspend-to-RAM state. (I can wake it by pressing the Fn key or closing & then re-opening the lid.) * Alas, about half of the time things don't work: the "moon" light starts blinking... but it keeps on blinking, the disk & fan stay running, and the system is hung: it won't respond to *any* keyboard input (including Fn, Fn-F4, and CTRL-Alt-Del). To regain control I have to power-cycle the system (==> unclean shutdown ==> need to re-fsck filesystems on reboot).
More Information, History, dmesg ================================ Note that this issue is with suspend-to-RAM, not suspend-to-disk (via tphdisk et al). I had similar problems in 2007 on a T41p running 4.1-stable (http://marc.info/?l=openbsd-misc&m=118157353605570&w=1). The problem turned out to be with the Radeon video driver. The workaround (http://marc.info/?l=openbsd-misc&m=118403957129081&w=1) was to switch to the VESA video driver (specified in /etc/X11/xorg.conf). This completely solved the problem for me, at the (trivial) cost of loosing hardware video acceleration and the XVideo extension. When 4.2 came out, I found that the VESA workaround was no longer necessary: suspend-to-RAM worked fine with the autoconfigured Radeon driver (no /etc/X11/xorg.conf) with XVideo and hardware acceleration too. Unfortunately, changing video drivers hasn't helped with my current T42 running 4.4-stable: the problem symptoms I described above (hangs about half of the time I suspend) are the same for all three of the following configurations: * let X autoconfigure everything (i.e. /etc/X11/xorg.conf does NOT exist; X detects the Radeon video and loads the Radeon driver) * /etc/X11/xorg.conf exists and specifies the Radeon driver * /etc/X11/xorg.conf exists and specifies the VESA driver (I checked /var/log/Xorg.0.log and verified that X is indeed loading the VESA driver) In a recent thread on openbsd-tech discussing similar problems with some other Thinkpad models, Dan Harnett suggested (http://marc.info/?l=openbsd-tech&m=123127247930921&w=1): > Does your system suspend/resume fine when not in X? If so, a workaround > with zzz is to create scripts named /etc/apm/suspend and /etc/apm/resume > to switch out of X before suspending, and switch back after resuming. > You can use wsconsctl with the display.focus variable to do so. I tried this, but it didn't help. The system would nicely switch out of X, and back in to X if it resumed... but it would still hang (same symptoms as above) on about half of my suspend attempts. So... Can anyone suggest how to get suspend-to-RAM to work reliably on this T42? [One other point that might be relevant: My /etc/fstab lists the usual /, /var, and /usr partitions, /tmp and /usr/tmp mfs, then /data, but not /home. /home is an svnd-encrypted filesystem mounted on top of /data/home.{dat,salt}; when I boot I login as root and (run a perl script which runs) vnconfig & mount to bring /home up, then logout and login as my normal username (with home directory under /home) before starting X. I don't use xdm.] dmesg: --- begin dmesg --- OpenBSD 4.4-stable (GENERIC) #0: Wed Jan 21 13:04:22 EST 2009 r...@oxygen.astro.indiana.edu:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) M processor 1.80GHz ("GenuineIntel" 686-class) 1.80 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 = 2146398208 (2046MB) avail mem = 2067062784 (1971MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 02/27/06, BIOS32 rev. 0 @ 0xfd750, SMBIOS rev. 2.33 @ 0xe0010 (61 entries) bios0: vendor IBM version "1RETDOWW (3.20 )" date 02/27/2006 bios0: IBM 2373997 apm0 at bios0: Power Management spec V1.2 apm0: battery life expectancy 100% 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 0xe0000/0x10000 cpu0 at mainbus0 cpu0: Enhanced SpeedStep 1800 MHz (1340 mV): speeds: 1800, 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 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 M10 NP" rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) agp0 at vga1: aperture at 0xd0000000, size 0x10000000 drm at vga1 unsupported 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 00:16:41:ab:96:3c ath0 at pci2 dev 2 function 0 "Atheros AR5212 (IBM MiniPCI)" rev 0x01: irq 11 ath0: AR5213 5.6 phy 4.1 rf5111 1.7 rf2111 2.3, WOR1W, address 00:05:4e:45:c8:39 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 compatibility wd0 at pciide0 channel 0 drive 0: <Hitachi HTS541616J9AT00> wd0: 16-sector PIO, LBA48, 152627MB, 312581808 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, initiator 7 cd0 at scsibus0 targ 0 lun 0: <TOSHIBA, DVD-ROM SD-R9012, 1121> ATAPI 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: 1GB 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 0x41445374 (Analog Devices AD1981B) ac97: 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 com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo 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 lpt2 at isa0 port 0x3bc/4: polled aps0 at isa0 port 0x1600/31 npx0 at isa0 port 0xf0/16: reported by CPUID;
