Hi,
I installed cgroup-bin on my system (Ubuntu 10.10, kernel 2.6.36), and
experienced similar problems as the original bug reporter, so I'm
reopening this bug. My system would suspend fine, but would not be able
to resume from it afterwards, requiring a hard reset.
I played around with the configuration files a bit, and managed to fix
the problem by disabling the creation of a default group (/sysdefault)
by editing /etc/default/cgconfig. I haven't experienced the problem
since that change. I'm pasting the contents of the relevant portions of
my config files (which I have changed from the defaults). If there are
other test cases you would like me to try, I can do that and report back
the results.
---/etc/cgconfig.conf---
mount {
cpu = /mnt/cgroups/cpu;
# cpuacct = /mnt/cgroups/cpuacct;
# devices = /mnt/cgroups/devices;
}
group root {
cpu {
}
}
group desktop {
cpu {
}
}
group shell {
cpu {
}
}
---/etc/cgconfig.conf---
---/etc/default/cgconfig---
# Service cgconfig can create a default group in all mounted hierarchies
and
# move all processes there on boot. If no default rule is specified in
# /etc/cgrules.conf, the default group is named '/sysdefault'.
# This automatically created group(s) can be useful e.g. when using
'cpu'
# controller to limit cpu.shares of this default group and allowing some
more
# important group take most of the CPU.
#
# By default, create these groups:
#CREATE_DEFAULT=yes
# Uncomment following line to disable creation of the default group on
startup:
CREATE_DEFAULT=no
