Here is a dmesg log from september, running the PCI Nvidia 8400GS rev.2 with nouveau on a K8 non-AGP host with Nvidia C51 PCI Express bridge. The GPU is driven by nouveau. So at this time I at least managed to connect through SSH while there was no display. The dmesg log reports a GPU lockup.
Yet again, this PCI GPU is known to work with nouveau driver when plugged into an Intel platform. Here may be the interesting parts: ``` [ 52.256093] nouveau 0000:05:00.0: DRM: core notifier timeout [ 54.256228] nouveau 0000:05:00.0: DRM: base-0: timeout [ 54.256455] Console: switching to colour frame buffer device 240x67 [ 54.256542] nouveau 0000:05:00.0: fifo: DMA_PUSHER - ch 1 [DRM] get 0000000000 put 0000000000 ib_get 00000002 ib_put 00000003 state a0000000 (err: IB_EMPTY) push 00406040 [ 54.256633] nouveau 0000:05:00.0: fifo: DMA_PUSHER - ch 1 [DRM] get 0000000000 put 0000000000 ib_get 00000003 ib_put 00000011 state a0000000 (err: IB_EMPTY) push 00406040 [ 54.256687] nouveau 0000:05:00.0: fifo: DMA_PUSHER - ch 1 [DRM] get 0000000000 put 0000000000 ib_get 00000011 ib_put 00000020 state a0000000 (err: IB_EMPTY) push 003020b0 [ 54.256740] nouveau 0000:05:00.0: fifo: DMA_PUSHER - ch 1 [DRM] get 0000000000 put 0000000000 ib_get 00000020 ib_put 00000033 state a0000000 (err: IB_EMPTY) push 00406040 [ 54.256811] nouveau 0000:05:00.0: fifo: DMA_PUSHER - ch 1 [DRM] get 0000000000 put 0000000000 ib_get 00000033 ib_put 00000049 state a0000000 (err: IB_EMPTY) push 003020b0 [ 54.725747] nouveau 0000:05:00.0: DRM: GPU lockup - switching to software fbcon [ 54.808979] nouveau 0000:05:00.0: fb0: nouveaudrmfb frame buffer device [ 54.809352] [drm] Initialized nouveau 1.3.1 20120801 for 0000:05:00.0 on minor 1 ``` ** Attachment added: "dmesg on Linux 5.4.0-47-generic, K8 platform (PCIe host, C51 bridge), Nvidia 8400GS rev.2 PCI with nouveau" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1902795/+attachment/5431331/+files/dmesg.linux-5.4.0-47.Dell_OptiPlex_740+K8-C51_Nvidia-8400GSr2_PCI-nouveau.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902795 Title: PCI graphics broken on AMD K8/K10 platform (while it works on Intel) verified from Linux 4.4 to 5.10-rc1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1902795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
