Hi all,
am a little stuck with suspend/resume on my ubuntu breezy system with a
vanilla 2.6.14.3 kernel built according to
http://www.columbia.edu/~ariel/acpi/acpi_howto.html
Can't get it to suspend cleanly in normal runlevels, but when I boot to
single user mode without vesafb, fbcon etc. and if I stop next to
everything (NetworkManager, pcmcia, alsa etc.) and then unload all sorts
of modules I can get the system to suspend ... though it seems to hang
with a line "Shutdown: hda" till I hit Enter.
Now, when I resume, I get:
Thawing cpus ...
Booting processor 1/1 eip 3000
Initializing CPU#1
Stuck ??
Inquiring remote API #1...
... APIC #1 ID: failed
... APIC #1 VERSION: failed
... APIC #1 SPIV: failed
Error taking cpu 1 up: -22
Kernel panic - not synching: Not enough cpus
While I tend to agree that I could use some more CPUs I don't panic about
it ;)
Anyway, from what I see on this list the code that actually gives this
output seems to be in some of the required patches mentioned here. Is it
safe to assume that 2.6.14.3 includes the patches needed for
suspend/resume on a P4 with SMP/HT/PREEMPT in the kernel?
TIA,
Karl.

I think it's yes.
Could you please try the CPU offline and online in the system?
just do
offline:
echo 0 > /sys/devices/system/cpu/cpu1/online
online:
echo 1 > /sys/devices/system/cpu/cpu1/online
please check if the CPU1 is correctly online after that.
Thanks,
Shaohua

Seems to work,
will try once more in single-user mode with all services stopped and
modules unloaded like when I suspended and keep you posted.

I don't know if it solves your problem, but i had to activate "Support
for hot-pluggable CPUs (Experimental)" (CONFIG_HOTPLUG_CPU=y) in kernel
to get suspend to disk working with my Pentium 4 HT. Maybe it helps.

Hi Christoph, Shaohua,
I do have hotplug_cpu configured into my kernel and disabling/enabling
CPUs works just as well in the situation where I did my suspend, s.
below.
Could it be the setting idle=halt is causing problems? I need that (or
max_cstate=1 to keep my CPU up to speed) ... otherwise I get boottimes
of an hour) found a patch that didn't help me, so I sticked to the boot
param. Haven't gotten round to testing without the param because it
would take a matter of hours to boot and suspend :S
Probable cause here?
Thanks,
Karl.

Hi Christoph, Shaohua,
I do have hotplug_cpu enabled and disabling/enabling cpus works in the
same situation as the suspend after which the resume does not.
Could my setting of idle=halt be a problem? I need it to work around a
boot up problem.
Thanks,
Karl.

Might be an issue fixed in latest kernel. Please try.

Not sure, you should really try with 2.6.15-rc...
Does resume work for you if you compile noSMP kernel?
Can you find out which driver breaks suspend?
