xsession-errors as copied during a successful session, after reboot
Quite a few errors, even when all seem to go well. Any pointer welcome, thanks.
"timeout by message bus" implies dbus is either stuck or crashed, which would essentially give the symptoms described here. Still happens, as usual KDM paused, then without changing or un/plugging anything, but doing a simple reboot, it opened just fine. Captured a new set of logs & messages, diff'ing paused and good (ignoring numbers using KDiff3) dmesg : all seem identical and almost in the exact same sequence in both cases, from messaging start, until usb enumeration (included): [ 3.341183] usb 4-2: new full-speed USB device number 2 using uhci_hcd [ 3.567840] usb 4-2: New USB device found, idVendor=0b05, idProduct=1712 [ 3.567848] usb 4-2: New USB device strings: Mfr=0, Product=0, SerialNumber=3 [ 3.567856] usb 4-2: SerialNumber: 0194E8-5B-0002 From there, in paused only, plenty of these : [ 3.726204] hub 6-0:1.0: unable to enumerate USB device on port 1 [ 4.891239] hub 6-0:1.0: unable to enumerate USB device on port 1 [ 6.056202] hub 6-0:1.0: unable to enumerate USB device on port 1 Would this be a cause or consequence of dbus being stalled ? (diff to be continued) No new occurrence in several months |
Created attachment 560586 [details] xsession-errors as copied from tty2 during the "pause", before reboot Description of problem: KDE session "sometimes" fails to initialize correctly. Version-Release number of selected component (if applicable): Please help triage, not sure which component is responsible. Running Fedora 16 KDE, strictly stable packages so far, up-to-date, few extras. (hence current KDE is 4.7.4). How reproducible: Recurrent but *not* always. Once every 5 or 6 KDE session init, maybe. So far, never occurred twice consecutively. Steps to Reproduce: 1. Boot computer until KDM screen shows up 2. Init KDE session Actual results: KDE session "sometimes" "fails to initialize correctly. KDM splash screen get stuck after showing the last icon (the KDE one). Expected results: KDE session always open correctly. Additional info: Issue has occurred since fresh install I think (i.e. it was already occurring before "heavier" system customization such as replacing nouveau with kmod-nvidia, enabling desktop effects or adding panel applets e.g. lancelot, and awn is installed but *not* autostarted). Attached xsession-errors as copied from tty2 during the "pause", before reboot. Attached xsession-errors as copied during a successful session, after reboot. During the pause, there is (little) disk activity for a minute maybe. Then the system seems to be waiting forever with no activity. After some time (minutes) a sound is played (see xsession-errors). Later again, plasma desktop shows up but is unusable: * no icon in default desktop folder applet * clicking default panel has no effect. * error dialogue is already open and shows the message « Cannot talk to klauncher: Message did not receive a reply (timeout by message bus) » Workaround: Switch tty (Alt+F2), at this stage or while waiting, login and `reboot`. Then, after reboot, KDE session opens with no errors (every time so far).
