[Bug 993202] Re: lircd crashing on boot in precise. Can be restarted and then stays up

 

I'm wondering if more information is needed.  If someone can point me to
some detailed instructions on how to compile the offending driver with
symbols for Ubuntu, to provide a more meaningful stack trace I'd be
happy to try.  This bug is causing me grief one out every two boots.

Also, although I have only seen it twice, I have experienced a system
lockup long after boot, where I'm pretty sure an LIRC bug trace was
generated on reboot.  This may or may not be the same problem, as the
LIRC crash could have just been sitting there from the initial boot, and
just got reported on the reboot.

Title:
  lircd crashing on boot in precise.  Can be restarted and then stays up

Status in “lirc” package in Ubuntu:
  New

Bug description:
  On my fresh install of Precise Ubuntu, I am suffering an lircd crash
  on boot.  This occurs most boots and apport has sent a few error
  reports in, but I didn't see an official bug open yet.  I am using a
  usbuirt receiver.  Judging by the SegvAnalysis, it looks like a null
  pointer deference.

  Some interesting information is that once the system is booted, I can
  restart lircd using '/etc/init.d/lircd restart' and the daemon starts
  and stays stable (up for days no new crashes).  This makes me
  suspicious that this could be an initialization race where the driver
  is trying to access something that is not yet available or initialized
  during the boot strip.

  I am attaching the crash report along with an included file that
  contains button signal definitions that is referenced in my lircd.conf
  file.
