[Cause] From upstream developer: The switcheroo code needs more work to switch properly on some systems it seems. There are a set acpi methods required to activate/deactivate the respective gpus. The drivers need to load and initialize active hw. If the hw is not active when the driver loads, then the hw is not set up properly and it won't work. Probably some ordering issues in how the switcheroo acpi methods are called. [Workarounds] Several options: 1. If your BIOS includes functionality to disable the Intel card, use BIOS settings to select which chip to load. 2. Disable KMS by adding `radeon.modeset=0` in the boot line. Note that the default radeon gallium driver only works with KMS, so YMMV. [Original Report] I'm running natty, and every since the upgrade to 6.14.0 I've been unable to consistently boot. After some discussion in the forums, I tried repeatedly to boot into recovery mode. In most cases, I got a black screen.

@harry I don't know if it means anything, but in newer kernels you may be unable to use that command, since /sys/kernel/debug may not be owned by you. A quick and dirty (if dangerous) solution would be to change the first line to chown username(:group) /sys/kernel/debug/ -R where username is again your username and :group is the optional argument for the group ownership of the folder Back to the bug, though, I did note one related oops in 50 boots (looking through my logs). I did note when it happened - it did cause a boot failure, but I did not give the evergreen error. Rather I got the gart_set_page error. However, it didn't cause a kernel dump like in the bisects. I only believe that the gart_set_page error to be related because it does not show up in kernels which were susceptible to the evergreen_cp_start oops. This still does not explain the race condition. FWIW I did some plotting out of the bisects on paper and found that if there was a commit that fixed the gart_set error it was between bisects 014 and 017. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

AceLan: The problem right now is that I suspect that the patch doesn't actually do anything to directly fix the problem. I.e., that the patch fixes this oops is just a side-effect of burning more time before the driver tries to access the hardware or something like that.

[Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
I've been looking at the patch we identified as fixing the problem, but I can't work out any causal relationship between what it does and the GPU being on when nouveau probes. I've inquired about it on the upstream bugzilla to see if I'm missing something. But I'm beginning to suspect that the patch alters the timing of things enough to prevent the problem from being triggered. ** Changed in: linux (Ubuntu) Status: Incomplete = In Progress -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
Hi Seth, One bad experience I have had since installing the patched kernel. After countless good boots I decided to add the following lines to /etc/tc.local in order to use switcheroo: chown username /sys/kernel/debug/vgaswitcheroo/switch # change username with your user name echo OFF /sys/kernel/debug/vgaswitcheroo/switch Everything seemed to work for the first 5 or so boots but then I started getting the blackscreens again. The message was similar but not the same. Unfortunately I didn't manage to get a screen of it. Once I got back into my desktop I removed the lines from rc.local and then the issue disappeared. I've gone ahead and added the lines again to see if I can recreate the issue but so far nothing. Not sure if this info is of any use to you at all but I thought I would share just in case it would. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Cause] From upstream developer: The switcheroo code needs more work to switch properly on some systems it seems. There are a set acpi methods required to activate/deactivate the respective gpus. The drivers need to load and initialize active hw. If the hw is not active when the driver loads, then the hw is not set up properly and it won't work. Probably some ordering issues in how the switcheroo acpi methods are called. [Workarounds] Several options: 1. If your BIOS includes functionality to disable the Intel card, use BIOS settings to select which chip to load. 2. Disable KMS by adding `radeon.modeset=0` in the boot line. Note that the default radeon gallium driver only works with KMS, so YMMV. [Original Report] I'm running natty, and every since the upgrade to 6.14.0 I've been unable to consistently boot. After some discussion in the forums, I tried repeatedly to boot into recovery mode. In most cases, I got a black screen.

[Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
Bisect 013 booted ok 24 times out of 30. 3 of the remaining times failed with an afaics unrelated oops in azx_interrupt in the snd_hda_intel driver. The last 3 times there were oops'es which didn't manage to get sufficiently logged on the tty to see where they were (the computer froze either before logging the relevant line, or after having scrolled it off the screen). I think it's most likely that those were in snd_hda_intel as well, since some other boots with that oops froze before logging the oops entirely. So my conclusion is that bisect 013 is not affected by the evergreen_cp_resume bug. I therefore didn't test 012 since it should work by implication under the bisect assumption. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Ok. So far I've had 11 consecutive successful boots with bisect012 I took another look at 005. While the screen goes black and I can bring up no TTY, kern.log shows no evergreen_cp_resume errors. Furthermore, the system eventually gets to the gdm login screen (I can hear the ding noise and can move my cursor and keys in order to restart the system, blindly), but the screen is still black. I managed to properly boot to the gdm login screen 20 times consecutively. Furthermore, I didn't get any kernel panics. As it doesn't appear exhibit the evergreen_cp_resume error, I believe for the purposes of the bisect that 005 should be in the good category, with 001 and 004 (and, by my testing, 012) As for the _gart_unbind error, I will hold off on reporting it unless I see it again, since I have only seen it on a bisect. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
I'm trying to construct a list of good and bad commits to use for starting a new bisection run. Please take note that it only takes a single occurrence of the evergreen_cp_resume oops to qualify a commit as bad, so there's no need to continue testing once you've seen that oops. I do agree that the radeon_gart_unbind oops looks different, so that shouldn't be considered a failure for the purposes of the bisection. Here's the list I have now. Bad builds: 000 003 005 006 007 008 009 010 011 Good builds: 001 004 Inconclusive: 005 Martin, just to verify -- with each of the builds you've indicated have failed for you, you've verified that you're getting the evergreen_cp_resume oops? josejuan05, when you tested build 005, did you verify that you were getting an oops in evergreen_cp_resume? If so, we can move that one to the bad list. Once this is all sorted out I'll use the information to seed a new bisection and start providing more builds to test.

Because testing good bisects is tedious, I went backwards: Bisect 005 is inconclusive since it bugs out with no tty output. Got one kernel hang, but since there's no tty output I don't know if it's this bug or not (nothing in kern.log from that boot either). Bisect 004 does not show the bug after 30 boots. @josejuan05: I suspect the radeon_gart_unbind oops is unrelated. I have seen it too, as well as another user in comment #17.

Thanks for checking, Martin. I was afraid that might happen with this bug. Can you also try the other builds before 006 that reported as good (001, 004, 005) and see if any of those fail? It's best if we can get as many testers as possible for each build. It's pretty clear when we get a bad result, but with the good results it's a lot less clear whether or not it's really good.

Since I've always gotten the bug in all the bisects I've tried, I thought I better reverify bisect 006 which has been reported as working by others.

[Side note: Had to install module-init-tools from oneiric to satisfy deps in these bisect builds.] Just to double check a little, I've tried the three latest bisects 007-009, and I've seen the oops in evertgreen_cp_resume at least once in each of them. However, the trig ratio is fairly low for me - bisect 009 gave the oops only 2 times out of 10, which means that to conclude its absence with a reasonable degree of certainty would require 50 boots or so. I also consistently get the no backlight bug with all builds (is there a separate report for that?). If one isn't aware of that issue, a successful start (wrt this bug) may be confused with a hang with no tty output. Btw, bisect 007 also gave an oops in radeon_gart_unbind. It was not inside any pci probe stuff but rather in some sort of cleanup code inside drm_release. I can attach the log if it's interesting. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

The status is that there are multiple reports of this being fixed in kernel version 3.0, and if this is true then the issue is fixed for oneiric. We're currently undergoing a process known as bisection to identify what changes fixed the problem in 3.0 so that the problem can be fixed in earlier versions.

First of all, bisect003 crashes as well, with or without headers. I looks like I kinda jumped to a conclusion too fast, as I am unable to reproduce the no-header-boot link.

[Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
Hi Seth, thanks a lot for clarifying. I've now tested the the three bisects and bisect000 crashes while bisect001 boots every time. I have no problems with CPU use either. For me however, bisect002 also crashes during start-up (two out of three times). As a side note, I had to install the headers of the bisects to make it crash, if I didn't install the headers I could boot all the kernels. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
Re: [Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
Hrm, I've got a lurking suspicion that this issue has a timing component (and that could actually be why it works in 3.0, not that it's really fixed but that the timing that some change in timing makes the problem much harder to trigger). If your CPU is being pegged then that could be affecting the results. We'll mark this one as good for now, but if the bisect goes bad we may come back to this point.

Are these bisects between 2.6.39-1 and 3.0-rc1 or between 2.6.39 and 3.0-rc1?

[Ubuntu-x-swat] [Bug 727620] Re: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics)
@Ap. Syvertsen: Let's try to lay out everything clearly to make sure there isn't any confusion. The swapping of the meanings of good and bad are bound to cause confusion, so let's use the usual meanings for any discussion with the understanding that the meanings are swapped *only in the bisect logs.* You said, My linux crashes occasionally during startup with kernel 2.6.39-1 with this kernel BUG, while I'm unable to produce this on 3.0-rc1. I took that to mean 2.6.39.1 is bad, i.e. exhibits an oops message similar to that in the bug description. And version 3.0-rc1 does not exhibit the oops. Is that understanding correct? It's a little problematic to bisect between 2.6.39.1 and 3.0-rc1. The stable kernels (anything with the fourth component of the version number, i.e. 2.6.39.y) are somewhat of a branch off of normal kernel development, and the bisection will go more quickly if we start with 2.6.39. This version should still have the bug if 2.6.39.1 does, unless it was fixed and then broken again, but that's unlikely. It can't hurt to verify that 2.6.39 really does have the problem however. So I started the bisection by marking 2.6.39 as bad (i.e. good in the bisect log) and 3.0-rc1 as good (i.e. bad in the bisect logs). git picked an intermediate version for testing, and that is what the bisect000 build represents. That is correct so far as my understanding of the situation as communicated above is correct. Does that make sense? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Unfortunately I don't have the laptop around where the bug showed up originally for me. I'll be there again on one of the next weekends. But be warned, I thought the bug has gone after updating natty a two weeks ago. I happily installed packages, got googleearth running, everything looked great, and than ... after next reboot - loose loose loose.

[Cause] From upstream developer: The switcheroo code needs more work to switch properly on some systems it seems. There are a set acpi methods required to activate/deactivate the respective gpus. The drivers need to load and initialize active hw. If the hw is not active when the driver loads, then the hw is not set up properly and it won't work. Probably some ordering issues in how the switcheroo acpi methods are called. [Workarounds] Several options: 1. If your BIOS includes functionality to disable the Intel card, use BIOS settings to select which chip to load. 2. Disable KMS by adding `radeon.modeset=0` in the boot line.

No one has identified what patches fix the issue, if it is indeed fixed at all. The thing to do now is to test these kernels on more affected machines, and if it fixes the problem universally we can try to find the fix and backport it. You can get mainline kernels for Ubuntu from the following link: http://kernel.ubuntu.com/~kernel-ppa/mainline/ I don't know exactly what version 2.6.39-git19 corresponds to, but a 3.0-rc3 is definitely available. If you find a build that does fix the problem it would also be useful to move backward one version at a time until you find the last version that is still broken. I'll also look to see if I can find out what changes might have fixed the issue.

@Jean, thanks for testing. I don't see anything in the radeon driver changes that looks like it obviously fixes the issue, but I've identified a handful that could be responsible. These commits were introduced between 2.6.39-rc5 and -rc7. What would be most helpful right now would to be able to state something like, version x doesn't work but version x+1 does.
