Description Tan Zheng Da 2001-06-24 05:36:50 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2r1 i686; en-US; rv:0.9.1)
Gecko/20010608

Description of problem:
Kernel 2.4.3-12 released by Red Hat, compiled with ReiserFS into the kernel
and disabled ReiserFS internal checking, running on a root ReiserFS system.
 When system is shut down, it hangs at the stage "Unmounting file
systems:".  Pressing Ctrl-Alt-Del here gives a warning: "shutdown: warning:
cannot open /var/run/shutdown.pid".  Problem did not exist on kernel 2.4.2-2.

How reproducible:
Always

Steps to Reproduce:
1.Your system should be running ReiserFS on root partition (see
http://cambuca.ldhs.cetuc.puc-rio.br/ )
2.Install kernel-source-2.4.3-12
3.make oldconfig using configs/kernel-2.4.2-i686.config
4.make menuconfig and edit File Systems, change ReiserFS to compile into
the kernel instead of as a module.  Disable internal code checking for ReiserFS
5.Compile kernel and install kernel.
6.Reboot into new kernel 2.4.3-12
7.Log in as root
8.Run 'shutdown -h now'
	

Actual Results:  When you reach 'Unmounting file systems:' on shutdown, it
will hang. Press "Ctrl-Alt-Del". Message "shutdown: warning: cannot open
/var/run/shutdown.pid" appears.

Expected Results:  It should have shut down cleanly.  The problem was not
present when I compiled kernel 2.4.2-2 with ReiserFS support and internal
checking disabled, for the exact same system.

Additional info:

The kernel was compiled with the steps according to my own documentation at
http://www.pobox.com/~tzd/linux/gateway/3350.html
Comment 1 Tan Zheng Da 2001-06-24 05:40:32 UTC 
Oops one typo.  Steps to reproduce, #3 should say:
make oldconfig using configs/kernel-2.4.3-i686.config
instead of kernel-2.4.2-i686.config.

investigating
Comment 3 Arjan van de Ven 2001-06-25 07:01:00 UTC 
Created attachment 21726 [details]
reiserfs patch
Comment 4 Arjan van de Ven 2001-06-25 07:01:38 UTC 
Could you try applying the previously attached patch to your kernelsource and
see if that makes it work ?
Comment 5 Tan Zheng Da 2001-06-25 11:27:45 UTC 
Yes, the patch (id 21726) works.  I can shut down cleanly now.  Do you mind
explaining what the patch does (I don't know how to program)?  Thanks!
Comment 6 Arjan van de Ven 2001-06-25 11:36:19 UTC 
It removes a bugfix that was applied to our kernel for a race on module-unload,
however the bugfix was not tested for the "reiserfs is not a module" case.
It seems it deadlocked in that case due to the locking changes in the original
bugfix.
Comment 7 Tan Zheng Da 2001-06-25 11:41:11 UTC 
Thanks for the explanation.  Is it safe for me to continue using the patch?
Comment 8 Arjan van de Ven 2001-06-25 11:41:56 UTC 
Yes.
Comment 9 Tan Zheng Da 2001-06-25 11:44:17 UTC 
Great!  And thanks for the speedy resolution!

I had this exact same problem.  I seem to be having an issue recompiling the 2.4.3-12 from the source RPM.  Using the binary RPM of the 2.4.3-12 
kernel supplied by RHAT, the aic7xxx_mod driver is listed in my /etc/modules.conf, as the default aic7xxx driver to use.  When I recompiled this kernel 
from the source RPM, and I try to make an initrd image, it says it cannot find the aic7xxx_mod file.  After looking through my /li/modules/2.4.3 tree, I saw 
that only aic7xxx and aic7xxx_old are compiled.

Which one should I use to boot with Justin Gibbs' aic7xxx driver?  I'm guessing the aic7xxx.o file, but I'm not sure.  Why wouldn't the aic7xxx_mod driver 
compile from the source?
Comment 11 Arjan van de Ven 2001-06-26 13:18:42 UTC 
 aic7xxx.o is the new driver.
Justin Gibb's driver got renamed in Linus' / Alan's kernels, in the RPM build
we rename the driver to it's original "2.4.2-2" name to make sure our kernel rpm
keeps working for people using this driver.
