Something between v5.8 and v5.9 has resulted in periodically losing video. Unfortunately, I can't reliably reproduce it, it seems to happen every once in a long while---I can go weeks without an occurance, but it always seems to happen after my workstation has been idle long enough to screen blank and put the monitor to sleep. I'm using a single display (Dell 2405FPW) connected via DVI, running X (Xorg 1.20.x from Debian sid). I don't really do anything fancy, xterms, a browser or two, play the occasional video, but like I said, I can't reliably reproduce this. I've had it happen about 11 times since August. lspci -vv output is: 01:00.0 VGA compatible controller: NVIDIA Corporation G86 [Quadro NVS 290] (rev a1) (prog-if 00 [VGA controller]) Subsystem: NVIDIA Corporation G86 [Quadro NVS 290] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 28 Region 0: Memory at fc000000 (32-bit, non-prefetchable) [size=16M] Region 1: Memory at d0000000 (64-bit, prefetchable) [size=256M] Region 3: Memory at fa000000 (64-bit, non-prefetchable) [size=32M] Region 5: I/O ports at dc80 [size=128] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: [60] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee01004 Data: 4023 Capabilities: [78] Express (v1) Endpoint, MSI 00 DevCap: MaxPayload 128 bytes, PhantFunc 0, Latency L0s <512ns, L1 <4us ExtTag+ AttnBtn- AttnInd- PwrInd- RBE+ FLReset- SlotPowerLimit 25.000W DevCtl: CorrErr- NonFatalErr+ FatalErr+ UnsupReq- RlxdOrd+ ExtTag+ PhantFunc- AuxPwr- NoSnoop+ MaxPayload 128 bytes, MaxReadReq 512 bytes DevSta: CorrErr- NonFatalErr- FatalErr- UnsupReq- AuxPwr- TransPend- LnkCap: Port #0, Speed 2.5GT/s, Width x16, ASPM L0s L1, Exit Latency L0s <512ns, L1 <4us ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp- LnkCtl: ASPM Disabled;

The timeout message are consistent the error messages a little less so. If there's more debugging I can do when this happens, I'd love to know what it is. kernel config: http://audible.transient.net/~jamie/k/nouveau.config-5.10.0 dmesg at boot: http://audible.transient.net/~jamie/k/nouveau.dmesg -- Jamie Heilman http://audible.transient.net/~jamie/ _______________________________________________ Nouveau mailing list Nouveau@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/nouveau
