4.6 Hangs during Shutdown
I have upgraded to 4.6 from 4.4.1 via netpkg.  All problems with xnetconf and missing icons have been resolved but I still have a problem with the system hanging on shutdown.  It happens every time I shut down and hangs at the same point.  The last thing printed to the monitor screen before it hangs is:

I did some googleing on md devices and found that it has something to do with software RAID.  I did not knowingly install RAID, so I'm not sure why it's trying to shutdown these devices.  I checked GParted and found that there is a partition called /dev/md/0.  GParted indicates that the partition is unallocated, file system is unallocated and it's size is 512 B.  I never notice a /dev/md partition or directory before on previous installation of Zenwalk.  Do you think that it's this partition that trying to be stopped during shutdown?  If so, then why can't it be shut down. Why is it even there?

Thanks

Try to pass "acpi=force" to the kernel at boot time from lilo.conf (append)..

It seems there's an acpi problem in 2.6.21.1

No difference in my laptop with that option. For example, I see battery info in files, but panel plugin give's me 50%%.

EDIT:
It seems, it has been reported.

Still hangs after making change to lilo.conf

Hi!

I had the same problem with sysvinit-2.86-i486-46.7. The "acpi=force" option didn't help. I'm able to halt the system by logging out of xfce and then halting the system using the options in gdm.

On my last shutdown of the night, last night, it did shutdown.  I did an update to sysvinit-2.86-i486-46.10 some time after my last post to this topic so I'm not sure if it was the update or the change to lilo.  I'll try to back out the lilio change to see if it was the acpi=force or the sysvinit that did it.

I confirmed that I need the append="acpi=force" in lilo.conf.  The system shutdown normally with this passed and hangs when it's not passed to the kernel

I apologies fro going back on forth on this, but my system is still hanging, even with the acpi=force being passed to the kernel.  If i count right, my system has only completely shut down twice since I've upgraded to snapshot about a week ago.

What kind of motherboard is it ?

it happened to me and i think it is because of the external usb drive that i have. If you have a pen or a device like mine connect at the shuting down moment try removing it first. 

This way i could confirm my problem too 

BIOSTAR NF325-A7 Socket 754 NVIDIA nForce3 250 ATX AMD Motherboard.  Never had a problem with earlier ZW releases.
nope, no usb drive connected at shutdown, but will give it a try

Hmmm, there were/are known problems with the nForce3 chipset.  Don't ask me what they were, as I don't remember.  If you remember, nvidia didn't have the 3 out very long before going to the 4, which fixed many things wrong.  The 3 should be avoided when possible.  Since you are stuck for the moment, did you check for a BIOS update on the board?  They may have added some patches to help with your problem/s.  I suspect the newer kernels bring out some bugs in earlier working hardware.  Also, check in your BIOS that ACPI aware OS is marked yes and PNP OS is no.  For the most part Linux doesn't use/need the BIOS, but recently the kernels seem to be changing some of that.

Thanks for the suggestions.  I can't find any setting in my bios that is an obvious equivalent to your suggestion. There are several setting for both acpi and pnp, but I need to do some research to determine which are the correct one.  I'm also concern about any affects on Xp (I dual boot) if I make changes to the bios.

I had a similar problem with my snapshot-ed machine, but very briefly thanks to Mauricio's advice:

- I had upgraded (this morning) an -all-ok- machine with snapshot as mirror.
- The effect: it no longer switched off at the end of a shutdown.
- Upon Mauricio's advice, i checked a

netpkg list N | grep -v extra

  to find if any new non-extra packages would need installing; The resuling list (for my machine...
  run your own for your list  ) :

[N][ap] Found dmidecode-2.9-i486-1.tgz on the repository : not installed
[N][l] Found gd-2.0.34-i486-1.tgz on the repository : not installed

  A small session with netpkg xxx (fill in from the list above) and the same machine does
  shutdown ok again.

Hope it helps...

prfaasse,

I read your email from the mailing list and followed what was suggested by Mauricio.  My list of packages was shorter than yours, having four less packages.  I installed each package one at a time and reboot a few times after each install.  No change, still hangs.  I then reinstall those packages that did not show up in my list but where in yours (gphoto, liboil, lsscsi) and did the same routine, install one at a time and then do several reboots.  All resulted in the shutdown hanging at the same point.  As I read this I notice that I may have missed pidgin, although I can't imagine that reinstalling it will resolve my issue.

Note that all hangs are at the exact same point, right after the message “md: stopping all md devices.

Thanks
