Default Bug#645071: linux-image-2.6.32-5-686-bigmem: init crashes during runlevel switch

Package: linux-2.6
Version: 2.6.32-38
Severity: normal
Tags: squeeze

Steps to reproduce:
1. Reboot computer.
2. Boot into runlevel 2.
3. Switch to console and go to single-user runlevel:
# telinit 1
4. Enter root password and switch to runlevel 2 again:
# telinit 2
5. And now, as i understand, second init copy (which run by telinit) will
crash.

I can't reproduce this again without rebooting system, i.e. it occurs only
after reboot and only once.
Also, i can't reproduce this with previous kernel (=2.6.32-35squeeze2), and,
though, i don't sure that this is kernel bug, but it seems, like last kernel
upgrade (=2.6.32-38) triggers it.

This isn't a crash.

[...].

This warning message was added by the bug fix "TTY: ldisc, do not close
until there are readers". I don't believe that the warning a
regression; it's just reporting a problem that already existed.

If you would like to help us understand and fix the problem, please can
you test the attached patch, following the instructions at
<http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>. It should replace the warnings with log lines of the form
"tty_ldisc_reinit: refcount of <name> is still <number>" which you
should send back.

Ben.

Hi, Ben.

I am not sure, that i do all correctly, but it doesn't compile. Here
is what i get

Default Bug#645071: linux-image-2.6.32-5-686-bigmem: init crashes during runlevel switch

I try to compile with printk() instead of printk_ratelimited() in your
patch, and it's succeeded. Then i install it with

# dpkg -i ./linux-image-2.6.32-5-686-bigmem_2.6.32-38a~test_i386.deb
# dpkg --configure --force-depends-version linux-image-2.6.32-5-686-bigmem

and then try to reproduce this bug. Here is the result:

Default Bug#645071: linux-image-2.6.32-5-686-bigmem: init crashes during runlevel switch

I suppose, that result of previous attempt is not very useful, because
something is missed in the output (after "of" word). So, i rewrite
your patch a little:
[..]
+ printk(KERN_DEBUG "%s: refcount of %p (%s, num=%d, mag=%d,
flags=%d) is still %d
",
+ __func__,
+ tty->ldisc->ops, tty->ldisc->ops->name, tty->ldisc->ops->num,
tty->ldisc->ops->magic, tty->ldisc->ops->flags,
+ atomic_read(&tty->ldisc->users));
[..]

And here is the output from this patch:
