Using Ubuntu 10.04 with kernel 2.6.32 In KMS mode the system fails to suspend both to ram and to disk. The problem persists in single-user mode. I followed the instructions from https://wiki.ubuntu.com/DebuggingKernelSuspend After performing sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend" The output from dmesg points to [ 0.333831] hash matches /build/buildd/linux-2.6.32/drivers/base/power/main.c:433 [ 0.333853] block loop5: hash matches [ 0.333921] pci 0000:01:00.0: hash matches sudo lspci -vvnn | grep -A 17 01:00.0 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon Mobility M6 LY [1002:4c59] Subsystem: IBM Device [1014:052f] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping+ SERR+ FastB2B+ DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 66 (2000ns min), Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 11 Region 0: Memory at e0000000 (32-bit, prefetchable) [size=128M] Region 1: I/O ports at 3000 [size=256] Region 2: Memory at c0100000 (32-bit, non-prefetchable) [size=64K] [virtual] Expansion ROM at c0120000 [disabled] [size=128K] Capabilities: [58] AGP version 2.0 Status: RQ=48 Iso- ArqSz=0 Cal=0 SBA+ ITACoh- GART64- HTrans- 64bit- FW- AGP3- Rate=x1,x2,x4 Command: RQ=32 ArqSz=0 Cal=0 SBA+ AGP+ GART64- 64bit- FW- Rate=x1 Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: radeon Kernel modules: radeonfb, radeon
Does s/r work if you disable kms? (boot with radeon.modeset=0) Does s/r work if you enable KMS but disable AGP gart? (boot with radeon.agpmode=-1)
Yes, both s/r work if I disable KMS, but I lose the joy of KMS :( No, s/r do not work if I disable AGP gart. I have also tested with the mainline Ubuntu kernel linux-image-2.6.34-999-generic_2.6.34-999.201004211003_i386.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-04-21-lucid/ I have also tested using the xorg-edgers PPA, specifically, the package xserver-xorg-video-radeon Version: 1:6.13.99+git20100416.a69e749d-0ubuntu0sarvatt Please let me know if there's anything else I can do to help.
Does anyone know if pm-suspend performs any tricks on suspending? What about "pm-suspend --quirk-none"?
(In reply to comment #3) > Does anyone know if pm-suspend performs any tricks on suspending? > > What about "pm-suspend --quirk-none"? Yes. By default it will store its quirks in /var/cache/pm-utils/last_known_working.quirkdb (source: man pm-utils) Also, from /usr/share/doc/pm-utils/README.debugging: * If a parameter (or lack thereof) passed to pm-suspend and friends is causing problems, or you need to debug the suspend/resume process to work out what quirks are causing problems, you can use the ADD_PARAMETERS and DROP_PARAMETERS environment variables. To do this, create a file in /etc/pm/config.d, and add the following lines to it: ADD_PARAMETERS="--parameter-to-add --another-parameter" DROP_PARAMETERS="--parameter-to-drop --another-parameter-to-drop" If you want to drop all parameters (for testing purposes, or to work around bugs in HAL), you can use DROP_PARAMETERS="all"
