Sorry for spamming, but I guess that log_io_reader is called by nih_io_watcher which has been initialised by "nih_io_reopen" which I suppose is called when job starts?
So that would go back to my original finding, job dies and is restarted before we get signal about disk being writable, but at the time job has been restarted it succeeds in writing unflushed logs to the disk while calling log_io_reader Makes sense? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1447756 Title: segfault in log.c code causes phone reboot loops Status in the base for Ubuntu mobile products: Fix Committed Status in Upstart: New Status in upstart package in Ubuntu: Confirmed Bug description: We recently started getting reprots from phone users that their devices go into a reboot loop after changing the language or getting an OTA upgrade (either of both end with a reboot of the phone) after a bit of research we collected the log at http://pastebin.ubuntu.com/10872934/ this shows a segfault of upstarts init binary in the log.c code: [ 6.999083]init: log.c:819: Assertion failed in log_clear_unflushed: log->unflushed->len [ 7.000279]init: Caught abort, core dumped [ 7.467176]Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000600 To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1447756/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
