Bug 453269

Created attachment 310509 [details]
gdb backtrace of autofs

Created attachment 310515 [details]
kernel dump once found on the console during system shutdown

Following a problem report upstream, due to a stupid mistake that
I've made in the past, Al Viro has been looking at the autofs4
code and has pointed out several races (so far) and this looks
like one of them. I'm working to fix them as Al points them out
so hopefully they will make it into the mainline kernel sometime
soon.

How often do you see this?

Ian

I see it every time the 750mhz system is started and automounted /home/user is
accessed. On 2Ghz system sometimes I don't see the problem. The screenshot was
made on a 2Ghz system.

Right, no doubt it is one of the problems that Al has pointed
out, but still, the daemon shouldn't be doing this. I'll have
a look.

Ian

A debug log from the daemon may be useful, taken when this
happens with some indication of when it occurred so I can
relate it to the log.

If you can get a log, check out http://people.redhat.com/jmoyer
for instructions to ensure we get the log we need please.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
