Hi!
A moment ago I had an extremely slow resume with 2.6.37. So slow that I
aborted it.
It was at 37% as I looked and then took a minute or more for each percent.
I am using in kernel suspend to disk via hibernate 1.99 which uses sysfs
power state disk.
Anyone have seen something like this? This was the first occurence, and I
am using 2.6.37 for quite a while.
I am calling hibernate-disk from this script:
shambhala:~> cat /etc/acpi/hibernate-extra.sh
#!/bin/sh
# Zur Sicherheit gleich am Anfang alle ausstehenden Änderungen schreiben
sync
# Versuchen, möglichst viele LowMem Pages freizubekommen
# Dir Entries legt Ext4 offenbar auch ins LowMem
# Und mit zu wenig LowMem Pages klappt der Tiefschlaf mit
# Radeon DRM KMS nicht.
echo 3 > /proc/sys/vm/drop_caches
# Network Manager schlafen legen
# siehe /usr/lib/pm-utils/sleep.d/55NetworkManager
dbus-send --print-reply --system \
--dest=org.freedesktop.NetworkManager \
/org/freedesktop/NetworkManager \
org.freedesktop.NetworkManager.sleep
# Systemzeit in Hardware-Uhr speichern
/etc/init.d/hwclock.sh stop
# Uptimed stoppen, damit er die Rekorde schreibt
/etc/init.d/uptimed stop
# Zur Sicherheit hier nochmal alle ausstehenden Änderungen schreiben
sync
# Gutnacht
# /etc/acpi/hibernate.sh
#echo 1 > /sys/power/tuxonice/do_hibernate
#pm-suspend-hybrid
#pm-hibernate
hibernate-disk
# Uptimed wieder starten. Dabei schreibt er erneut die Rekorde
/etc/init.d/uptimed start
# Rekorde gleich schreiben
sync
# Festplatten-Parameter wieder setzen
/etc/init.d/hdparm start
# Systemzeit anhand Hardware-Uhr wieder setzen
/etc/init.d/hwclock.sh start
# Network Manager aufwecken
dbus-send --print-reply --system \
--dest=org.freedesktop.NetworkManager \
/org/freedesktop/NetworkManager \
org.freedesktop.NetworkManager.wake
I am echoing 3 onto drop_caches cause often in kernel suspend - as well as
TuxOnIce as I used it back then - was not able to free lowmem pages in
order for the image to be allocated after I switched to radeon kms which
seems to require quite some lowmem pages of its own, but I will post a
different mail about this one.
I am using
shambhala:~> cat /proc/version
Linux version 2.6.37-tp42-rtime-00004-g9eb63ce (martin@shambhala) (gcc
version 4.4.5 (Debian 4.4.5-8) ) #1 PREEMPT Thu Jan 13 10:59:19 CET 2011
which is 2.6.37 + some recursive mtime changes from Jan Kara, which should
only affect Ext3 and Ext4.
Ciao,
