The kernel you sent me recently, replaced the existing Utopic kernel 3.16.0-28, if I understood correctly this was a normal behaviour due to the identical version numbers, ... anyways:
NONE OF the original 3.16.0-28 kernel and the fresh kernel you sent me works, I see exactly the same crash view, perhaps in a bit slower performance, say I have to wait even 2 seconds to see the second phase of the crash, and again 2 seconds for the third phase. So the timing is a little bit slower, but not significantly slower. I made a repeated check with the kernels I tried earlier: the error is still there, I try to be careful not to reconfigure my system during the error discovery weeks. -- 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/1386534 Title: kernel dependent deterministic view crash on X startup Status in linux package in Ubuntu: Confirmed Bug description: kernel 3.13.0-37 and 3.16.0-23, but not kernel 3.13.0-36 The phenomenon: just when the user interface starts at the end of the Ununtu startup, the screen reamins in one solid color (very light grey, this is the everage of my colors), except for the topmost 3-4 scan lines, where one can see some sort of vibrating content. Sometimes there is a 1-3 seconds of normal operation just at the start, when Ctrl-Alt-F2 works, and swithing there one can work in the character terminal forever. But as soon as the disorder in the X view appears, even the Ctrl-Alt-F2 console change does not work visually, however a blindly stroken Ctr-Alt-Del is correctly executed. What I know: (1) on the core i3 based laptop there is no trace of this kind of view crash, while in case of the Phenom x6 1100t and Radeon HD 6570 based desktop machine the problem is fully deterministic. (2) the problem is distro independet, i.e.: I have it with Ubuntu 14.04 + kernel 3.13.0-37-generic, and also with Ubuntu 14.10 + 3.16.0-23-generic, and I do NOT have it with Ubuntu 14.04 + kernel 3.13.0-36-generic, and also with Ubuntu 14.10 + 3.13.0-36-generic. (3) In case of Ubuntu 14.04 in average every second or third boot gave a 1-3 seconds of grace period when I could escape to Ctrl-Alt-F2, while in case of Ubuntu 14.10 there is no such a short time slot when I could escape. (4) my configuration is set to fall into my only user account directly, I will do experiments, whether the problem is there, if the startup is without falling into an account. If I can, I will apport log files with produced with the 3.16.0-23-generic kernel as well, not only with the 3.13.0-36-generic. I try to send the remaining information after my work day, now I have to leave, sorry. --- .tmp.unity.support.test.0: ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDmesg: [ 11.299825] init: plymouth-upstart-bridge main process ended, respawning [ 11.329699] systemd-logind[1615]: Failed to start unit user@1000.service: Unknown unit: user@1000.service [ 11.329706] systemd-logind[1615]: Failed to start user service: Unknown unit: user@1000.service [ 11.332093] systemd-logind[1615]: New session c1 of user prohlep.
