[Kernel-packages] [Bug 1598935] Re: Ubuntu 16.04 won't properly boot due to radeon module issue
I have great news! The system is now booting properly! No more 20 minute wait to login! I noticed it with the update to the 4.4.0-42 kernel. So, this issue might have been fixed with either that kernel update or the previous, 4.4.0-38 kernel update. In any event, this is no longer an issue and this bug report can be closed out. I'll close it, if I can. :) Thanks! -- 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/1598935 Title: Ubuntu 16.04 won't properly boot due to radeon module issue Status in linux package in Ubuntu: Expired Bug description: When I boot an Ubuntu 16.04 live DVD on a Gateway system with an AMD A6-5400K APU, with an integrated Radeon HD 7540D graphics adapter, I get a black screen with no video image.

[Kernel-packages] [Bug 1598935] Re: Ubuntu 16.04 won't properly boot due to radeon module issue
Ok, I have another update. I managed to get SSH setup and was able to save some XOrg and dmesg logs. However, I think this bug report can be closed. Why? Because, I'm able to get full resolution video with the 4.4 kernel. This is what I've found: if I boot my Ubuntu 16.04.1 system normally, with "quiet splash" set in the GRUB default config file (/etc/default/grub), I'll eventually get full resolution video on terminal #7 *but* only after about 30 mins. Here's the situation: 1) I boot the system normally 2) I get a black screen for 30 "wall clock" minutes 3) After 30 mins, if I press Ctrl-Alt-F7, I get the Ubuntu login screen 4) I login as normal and get the Unity desktop at full resolution So, I'm not sure why it takes 30 minutes for things to work but this is the case. We don't reboot the system very often, so this might not be a huge deal even though we will want to get this fixed, at some point. So, from the perspective of this being a kernel bug, I'm not sure this bug report is valid. How do we proceed?

[Kernel-packages] [Bug 1598935] Re: Ubuntu 16.04 won't properly boot due to radeon module issue
Ok, I _finally_ have an update on this. I put another hard drive into the system, booted an Ubuntu 16.04.1 live DVD I burned today, and installed Ubuntu 16.04.1 on this test hard drive. When I booted the live DVD, the video issue occurred, so I re-booted and specified the "nomodeset" parameter. After doing that, I was able to get the system to boot and was able to successfully install Ubuntu 16.04.1. After the installation completed, the system booted *without* my having to specify the "nomodeset" parameter and the monitor was running at full resolution (1600x900 or something along those lines). So, I thought maybe the issue had been fixed with the 16.04.1 release of Ubuntu. I removed the test hard drive, reinstalled the primary hard drive, booted the system to Ubuntu 14.04.2, and performed an _upgrade_ to Ubuntu 16.04.1. After the upgrade completed, the video issue returned *sigh*. However, I'm now able to get SSH setup so I can collect the requested logs. I'm confused as to why a fresh install of Ubuntu 16.04.1 works but the upgrade doesn't. From what I understand, the AMD video driver is in the kernel and I would think the 4.4 kernel would be the same, regardless of the system being installed fresh vs being upgraded. As of right now, the primary hard drive has Ubuntu 16.04.1 installed, the video issue is present, and kernel version 4.4-31 (I believe) is running. Once I'm able to get SSH setup and get the logs transferred to another system, I'll attach them to this bug report.

[Kernel-packages] [Bug 1598935] Re: Ubuntu 16.04 won't properly boot due to radeon module issue
Thanks for the reply. With regard to SSH, I have access to only one system, the system on which I'm booting the live DVD. Ubuntu 14.04.2 is installed on the system and works just fine. So, I would prefer *not* touching this installation. I wanted to try the 16.04 live DVD to see if there might be any upgrade issues, once Ubuntu 16.04.1 is available. So, I'll see if I can get Ubuntu 16.04 installed on the current system, using a different hard drive. Once I'm able to do that, I'll install the upstream kernel and will conduct tests. I'll report back my findings once I'm able to do so.

[Kernel-packages] [Bug 1598935] Re: Ubuntu 16.04 won't properly boot due to radeon module issue
Thanks for the reply. Well, if I'm not getting any video I'm not sure how I could get SSH setup but I do have something interesting to report. When I boot the live DVD, leave the "set gfxpayload=keep" setting alone, and remove "quiet splash" from the kernel parameters, I can get the system to boot. How? I'm not sure. I wait for there to be no sound from the optical drive, which tells me the system has completed its internal boot process. Then I start pressing Ctrl-Alt-F1 through F12, trying to switch from X terminal sessions to a text-mode login session and eventually, I'll get a video signal, along with the desktop on the terminal I get from Ctrl-Alt-F7 (tty 7). So, perhaps I'm triggering something by doing this, I'm not sure. However, I do have a dmesg log generated *without* specifying "nomodeset". Now, something else worth mentioning. I have the system setup to *not* boot in UEFI mode, because I had problems with Ubuntu 13.04 (my first Ubuntu release) booting in UEFI mode. So, I disabled secure boot and enabled the "Legacy CSM" and the system boots reliably from the hard drive. When I boot the Ubuntu 16.04 live DVD in non-UEFI mode, I never get a chance to specify the kernel parameters. When I boot the live DVD in UEFI mode, I get a chance to specify the kernel parameters.

[Kernel-packages] [Bug 1598935] Re: Ubuntu 16.04 won't properly boot due to radeon module issue
Ok, attached is the output from "dmesg" after I booted from the Ubuntu 16.04 live DVD. Per the instructions here: https://wiki.ubuntu.com/DebuggingKernelBoot I changed "set gfxpayload=keep" to "set gfxpayload=text" After doing that, the wireless network adapter didn't work. Previously, the wireless adapter did work but I left the "gfxpayload" setting to "keep". I'm using a wired Ethernet connection right now. I also replaced "quiet splash" with "nomodeset", since without "nomodeset", I won't get any video. There was no "vt.handoff" setting when I looked at the default kernel parameters screen. Please let me know what other information you need.

Ok, this time, I have the live DVD booted with gfxpayload=text, "quiet splash" not specified, and "nomodeset" *not* specified. Once the optical drive stopped making noise, I pressed Ctrl-ALt-F1 and my monitor immediately got a signal. I then pressed Ctrl-Alt-F7 and got to the desktop. I'll attach the dmesg and Xorg logs now.

[Kernel-packages] [Bug 1568211] Re: Unable to boot
I'm experiencing this issue on my mom's computer, a Gateway system with an AMD A6-5400K APU (Radeon HD 7540D graphics). The behavior Jaap Woldringh describes is exactly what I'm seeing. I boot an Ubuntu 16.04 liveDVD and I get the black screen. If I reboot from the liveDVD and specify "nomodeset", the system boots but in low resolution. When I look at the Xorg.0.log file, I see the "No UMS support in radeon module" message. What's interesting is I booted the same liveDVD on another system, an HP with an AMD A8-5500k APU (Radeon HD 7560D graphics) and it booted just fine, no issues at all. My mom's Gateway system is currently running Ubuntu 14.04.2 without any issues and at full resolution. Of course, I would like to get this resolved before I attempt to upgrade her system to 16.04.1. :) Thanks! -- 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/1568211 Title: Unable to boot Status in linux package in Ubuntu: Incomplete Bug description: I upgraded overnight from Wily to Xenial.
