| ubot5` | Launchpad bug 1566726 in linux-lts-utopic (Ubuntu) "System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]" [Undecided,New] https://launchpad.net/bugs/1566726 | 08:52 |
| infinity | That sounds ungood. | 09:03 |
| infinity | jsalisbury: ^-- Care to escalate that a bit? | 09:03 |
| apw | kamal, ^ | 10:32 |
| jsalisbury | infinity, thanks for the pointer on that bug. yofel, I'll post a test kernel shortly. | 14:35 |
| jsalisbury | apw, kamal, looks like the offending commit is already reverted in -next: | 14:44 |
| jsalisbury | a907233 Revert "drm/radeon: hold reference to fences in radeon_sa_bo_new" | 14:44 |
| jsalisbury | 72a5cff drm/radeon: hold reference to fences in radeon_sa_bo_new | 14:44 |
| * jsalisbury is building a test kernel of -next for testing | 14:45 | |
| kamal | jsalisbury, ha! yup, I was _just_ confirming exactly that with Luis. | 14:45 |
| kamal | jsalisbury, that is indeed the fix, and yes, its already committed. How about you build a test kernel (either of the top of utopic-next, or with just that revert applied), so we can get the bug submitters to verify it? | 14:47 |
| jsalisbury | kamal, I have test kernel of the top of utopic-next building now. I'll have it verified | 14:48 |
| kamal | jsalisbury, very good, thanks | 14:48 |
| jsalisbury | np | 14:48 |
| kamal | jsalisbury, also fyi, I've determined that the problem should only affect 3.16 (so Utopic only, no other Ubuntu kernels) | 14:49 |
| jsalisbury | great | 14:49 |
| dschatzberg | hey all, I'm trying to test an upstream kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc2-wily/), how do I apply the patches provided? Applying them naively doesn't seem to set the permissions right? | 15:06 |
| genkgo | jsalisbury: exciting, coming really close now | 20:05 |
| genkgo | where can i look that bad commit 5044635f00, is that a commit from linus? | 20:05 |
| genkgo | i mean linus' repo linux on github | 20:06 |
| jsalisbury | genkgo, yes, it's in Linus' tree. That particular commit isn't the cause. That was just the tip of the kernel tree for that test kernel build. | 20:37 |
| genkgo | ok, i think i don't get what a bisect actually means | 20:37 |
| genkgo | i will read upon that | 20:38 |
| jsalisbury | genkgo, there is a wiki page that has some info: https://wiki.ubuntu.com/Kernel/KernelBisection | 20:38 |
| genkgo | jsalisbury: wonderful, i will read that! | 20:38 |
| genkgo | jsalisbury: ah, i get it, it just a fast way to pick a wrong commit | 21:21 |
| genkgo | just like you did by picking the latest good and first bad version of the kernel | 21:22 |
| genkgo | but only with those sha identifiers it's less obvious | 21:22 |
