------- Comment From mranw...@us.ibm.com 2018-12-06 02:22 EDT------- I recreated the problem where I could see the errors in dmesg (and the console) and then added the firmware to /lib/firmware/nvidia/gx100. After that: mranweil@ltc-wspoon5:~$ dmesg|grep -i nouv [ 6.632529] nouveau 0004:04:00.0: enabling device (0140 -> 0142) [ 6.632613] nouveau 0004:04:00.0: Using 32-bit DMA via iommu [ 6.632721] nouveau 0004:04:00.0: NVIDIA GV100 (140000a1) <snip> [ 7.061963] nouveau 0035:03:00.0: DRM: Pointer to TMDS table invalid [ 7.061966] nouveau 0035:03:00.0: DRM: DCB version 4.1 [ 7.063141] nouveau 0035:03:00.0: DRM: MM: using COPY for buffer copies [ 7.063154] [drm] Initialized nouveau 1.3.1 20120801 for 0035:03:00.0 on minor 2 mranweil@ltc-wspoon5:~$
So looks like the firmware from the current git tree addresses the error messages. I didn't do anything further with the driver. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1794055 Title: [Witherspoon-DD2.2][Ubu 18.10] [4.18.0-7-generic ] OS booting thrown with nouveau errors; OS booted successfully Status in The Ubuntu-power-systems project: Incomplete Status in linux package in Ubuntu: Incomplete Status in linux source package in Cosmic: Incomplete Bug description: == Comment: #0 - Kalpana Shetty <kalsh...@in.ibm.com> - 2018-09-15 23:55:13 == ---Problem Description--- [Witherspoon-DD2.2][Ubu 18.10] [4.18.0-7-generic ] OS booting thrown with nouveau errors Contact Information = kalsh...@in.ibm.com, preeti.tha...@in.ibm.com ---uname output--- root@ltc-wcwsp3:~# uname -a Linux ltc-wcwsp3 4.18.0-7-generic #8-Ubuntu SMP Tue Aug 28 18:20:56 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux Machine Type = Witherspoon DD2.2 LC Steps: 1.

Well, I think those message mean that the nouveau module can't find the firmware file as opposed to it being a FW issue. Might be a packaging issue if this is actually not causing any real issues. Probably best to mirror this to Canonical for their comment. == Comment: #10 - Chandni Verma <chand...@in.ibm.com> - 2018-09-24 03:25:35 == To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1794055/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
