Ondrej - aha! with the debug, this is making more sense now. Yes, since the ureadahead-touch job spawns a process in the background (ureadahead) and then the job itself exits, the log associated with the main job process gets added to the unflushed list. ureadahead then writes output and the NihIo is automatically serviced to flush the log to disk and set log->unflushed->len to zero. Later, 'initctl notify-disk-writable' gets called and the assert fires as all the output from both /etc/init /ureadahead-touch.conf and from the ureadahead daemon itself has already been logged.
Could you try the following which should be a minimal fix: http://paste.ubuntu.com/11095313/ Another point - the fact that ureadahead-touch is triggering the problem does point to an issue with that job - as can be seen, even when the script section ends (and that associated shell dies), 'ureadahead --daemon' continues and if it produces output, that gets logged. A simple work-around is to remove --daemon so that the job process and the log never become detached. -- 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
