Shutdown hanging

Message

When I shut down my newly installed gentoo system, it hangs, and the lat thing it says is:

* Saving random seed... [ ok ]

I have to kill the power at this point to do anything else.

Thoughts?

Doesn't it appear "System Halted" on the screen? Do you have ACPI enabled? Does it always happen? Does it happen with every shutdown command (halt, poweroff, shutdown)? These are my thoughts.

Hello.
I have the same problem at the filesystems unmounting.
I think it's due to the kernel 2.6.12-gentoo. Maybe I am wrong.
Since I've installed it, my computer hangs there.
ACPI is enabled.
Here are my thoughts.

I get the same thing - hangs when unmounting filesystems with 2.6.12-gentoo...

Same problem.

System freezes when "unmounting filesystems".

Have to reboot with Alt+Syst combos

Kernel : 2.6.12-gentoo
Baselayout : 1.11.12-r4
Udev 0.58

I have this problem since I upgraded to 2.6.12-gentoo and Udev 0.58.
But I don't know if the cause is 2.6.12-gentoo or Udev 0.58.

It's not udev-058 because i emerged it on 21st May.
I really think it's the kernel 2.6.12-gentoo.

Yup, I second that. Same problem here.

Probably some incompatibility between baselayout and kernel 2.6.12-gentoo, because the system can be shut down just fine with a "shutdow -h now"...

I love the outstanding 2.6.x stability

same here a workaround would be have your finger on the powerbutton and do
# reboot
and as soon as it says "[ ok ]" for unmounting local file systems press/push/flip the switch
that was before i used it as a router though. See gentoo's so cool that it shouldnt be turned off evar, therefor the programmers added this "feature" to protect us from ourselves.

I have the same problem, using vanilla-sources-2.6.12.1. I am fairly sure it's udev causing it though -- if i compile in devfs (which I've been using fo the last while) it runs and shuts down fine. however if i move to udev (which i did during the upgrade to 2.6.12.1 since I hear devfs is departing soon), it boots and runs fine, but hangs on shutdown.

I'm not using udev, so I don't think it's the problem...

And again, issuing:

Code: Select all

shutdown -h now

*Does work*, so it's probably definitely a problem with the way baselayout works?

It hangs if I shut it down via gdm...
I'm not too sure what the difference is, though. I thought it ultimately did the same thing, apparently not...

Ok guys, I seem to have solved it, but I did two things, and now I'm not too sure which did the trick.

1. I re-emerged baselayout.
2. I removed the "quiet" splash option on the kernel command line.

splash seems a little borked with kernel 2.6.12 still - the "silent" mode doesn't work properly... "verbose" mode seems ok, even though I don't get the splash background bitmap then...

But at least, I can seem to be able to shut down my computer now...

Does the "quiet" splash option really make the difference, doesn't it work with it?

I think my own problem is quite different.
I've updated my kernel to 2.6.12-gentoo-r1 and it continues to hang at FS unmouting.
At every reboot, it recovers my /home journal (ext3fs).
I also reemerged baselayout but nothing had changed.

Same here.

With a 2.6.11.x kernel "Removing dm-crypt mapping" was coming right after the "Unmounting filesystems", message. What if the problem was on the "dm-crypt" side rather than the "Unmounting FS" ??

MerlinTheWizard · Post by **MerlinTheWizard** » Sun Jun 26, 2005 1:11 am

Actually, I thought it did the trick, but it didn't quite.

I'm almost pretty convinced now that this problem is *entirely* related to fbsplash...

Actually, it seems like the kernel doesn't exactly "hang" while shutting down, but it becomes unresponsive due to fbsplash using most of the CPU time.

I'm almost certain that the bug is with fbsplash now...

Forget about this, i disable de Device Mapper Support and the Crypt Target Support in the kernel, then i unmerge sys-fs/cryptsetup and sys-fs/device-mapper and it's the same

Are you at least using framebuffer?

apmurray · Post by **apmurray** » Sun Jun 26, 2005 10:56 pm

I am using vesafb but no fbsplash and I am still getting this with gentoo-sources-2.6.12-r1

Yup, I tried disabling fbsplah and it didn't help... but I'm using vesafb in both cases...

I noticed something: if I shut my computer down after Gnome has started, but before doing anything in it, it will shut down properly...
But if, for instance, I start Totem and play some video, then close Totem and shut the computer down from Gnome, it will hang at "unmounting filesystems"...

So it still looks like some kind of video problem?
Can anyone try what I said to confirm this?

(Next step would be to try booting without framebuffer: I'm going to try that and report the results...)

I am having the exact same problem that you guys have described here. I am using vesafb, but not framebuffer.

That happens to me too. If I shut it down very close to boot time, it will work fine. But if I do any work on it, it will hang at "unmounting filesystems". I will play a little tonight to see if I can come up with anything.

I have the same problem too. It started when I updated kernel to gentoo-sources-2.6.12. System hangs at shutdown when unmounting drives. When i try unmount my ntfs partition by hand the system freeze too. I'm not using fbsplash and vesafb (radeonfb instead).
