Bug #: 46557 Summary: nouveau: nv40 display corruption in framebuffer and X lockups unless nouveau.noaccel=1 Classification: Unclassified Product: xorg Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau@lists.freedesktop.org ReportedBy: salah.coro...@gmail.com QAContact: xorg-t...@lists.x.org Created attachment 57574 --> https://bugs.freedesktop.org/attachment.cgi?id=57574 live dmesg before X was started When I start nouveau with 2D acceleration the framebuffer is unusable (typically displays frozen contents of the last shutdown), but the keyboard is responsive. Once X starts, the display is unreadable - anything to a tiled staircase picture to a partially solid grey screen, with no mouse cursor, and the keyboard locks up - no responsive from the caps/num/scroll locks keys, however it DOES respond to Magic SysRQ. The machine itself doesn't seem hard locked, though. The syslog is spammed with tons of message from the nouveau driver complaining about PFIFO_CACHE_ERROR, PFIFO_DMA_PUSHER: MEM_FAULT, INVALID_CMD, CALL_SUBR_ACTIVE, etc - varies wildly on each boot. Sometimes its only few errors, sometimes tons of them, but the end result is the same. Tried with the nouveau git tree on freedesktop 2/23. using nouveau.nofbaccel=1 clears up the framebuffer corruption, but the X display corruption/lockups still happen Display adapter: 00:05.0 VGA compatible controller: nVidia Corporation C51 [GeForce 6150 LE] (rev a2) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 2a34 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 Interrupt: pin A routed to IRQ 16 Region 0: Memory at fc000000 (32-bit, non-prefetchable) [size=16M] Region 1: Memory at e0000000 (64-bit, prefetchable) [size=256M] Region 3: Memory at fb000000 (64-bit, non-prefetchable) [size=16M] [virtual] Expansion ROM at c0000000 [disabled] [size=128K] Capabilities: [48] 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: [50] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: nouveau Kernel modules: nouveau -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
