[SOLVED] Hangs on System Shutdown

Manifold · 2011-10-13 19:23:01

Hello,

My Arch just started hanging on shutdown, I'll post the log from everything.log from point of initiating sudo poweroff from tty to the hang:

Oct 13 20:10:25 localhost shutdown[1537]: shutting down for system halt
Oct 13 20:10:25 localhost init: Switching to runlevel: 0
Oct 13 20:10:27 localhost syslog-ng[885]: Termination requested via signal, terminating;
Oct 13 20:10:27 localhost syslog-ng[885]: syslog-ng shutting down; version='3.2.4'

Here's uname -mrsn:

Anyone have any ideas?

EDIT: I've fixed this, but I have no idea why. I removed hwclock from rc.conf, and suddenly I can shut things down again. Does anybody know why? Also, don't I need hwclock? How is my system time still being displayed (in XFCE, for example) without it?

I was having this same exact problem, and its good to know that I can fix it by disabling hwclock. I'd prefer not having to do so either, preferring bugfixes to workarounds. What exactly does hwclock do?

Manifold · 2011-10-14 21:58:41

The man page states that it queries or sets the hardware (BIOS) clock. I'm not entirely sure why it's there - you can still sudo hwclock to access the time.

I'm a bit reluctant to set this as [SOLVED]... maybe [KLUDGED], though.

Why don't you add --debug into hwclock init script and see the output... Apparently [1] hwclock used to have such problems.

This is the /etc/rc.d/hwclock script,

#!/bin/bash

. /etc/rc.conf
. /etc/rc.d/functions

case $HARDWARECLOCK in
        UTC) HWCLOCK_PARAMS="--utc";;
        localtime) HWCLOCK_PARAMS="--localtime";;
        *) HWCLOCK_PARAMS="";;
esac

case "$1" in
        start)
                add_daemon hwclock;;
        stop)
                case $HARDWARECLOCK in
                        UTC) hwclock --adjust --utc;;
                        localtime) hwclock --adjust --localtime;;
                        "") hwclock --adjust;;
                esac
                rm_daemon hwclock
                ;;
        restart)
                $0 stop
                sleep 2
                $0 start
                ;;
        *)
                echo "usage: $0 {start|stop|restart}"
esac

Where exactly should I put --debug?

I guess the difference between me and this guy is that my system doesn't hang when I run hwclock as root. Only when shutting down.

Leonid.I · 2011-10-15 17:58:07

I think after each hwclock command in stop)...

Manifold · 2011-10-15 18:16:45

Thanks Leonid,

So basically, whenever the

/etc/rc.d/hwclock stop

command is issued (be it in shutdown, tty or in X), the hwclock issues something along the lines of:

sudo /etc/rc.d/hwclock stop
hwclock from util-linux 2.20
Using /dev interface to clock.
Last drift adjustment done at 945740615 seconds after 1969
Last calibration done at 973896678 seconds after 1969
Hardware clock is on UTC time
Assuming hardware clock is kept in UTC time.
Waiting for clock tick...
...got clock tick
Time read from Hardware Clock: 2011/10/15 18:13:37
Hw clock time : 2011/10/15 18:13:37 = 1318702417 seconds since 1969
Time since last adjustment is 372961802 seconds
Need to insert 2147483647 seconds and refer time back -144953139919.930267 seconds ago
Time elapsed since reference time has been -144953139919.930115 seconds.
Delaying further to reach the new time.

And just waits and waits...

I believe I fixed this by deleting/renaming /var/lib/hwclock/adjtime (after stopping /etc/rc.d/hwclock), and then setting a new time using

sudo hwclock --set --date="MM/DD/YY HH:MM:SS"

.
