Re: 2.6.9-rc3 software suspend (pmdisk) stopped working

[Mitch]

Hi,

Ok, here is the kernel messages attached. Nothing of real value in it as 
far as i can see (even with PM_DEBUG on), but you may spot something. 
Basically the suspend process appears to start but the machine is never 
powered off and the resume kernel routines are run immediately bringing 
the kernel/system back to it's resumed state. The *same* kernel config 
works on -rc2. If i hard power off the machine then i have to fsck my 
disks on bootup (as expected) and the suspended image is not loaded.
Clearly the latest patches have broken something but what ? Can anyone 
else without ACPI suspend on -rc3 ?

As i keep mentioning, i have a problem with *shutting down* not 
resuming. I'm assuming if a good memory image is written and machine 
powered off correctly i will be able to resume correctly (with the 
recent hihgmem fix). We should be looking at why APM BIOS shutdown 
routine is not working correctly.

My kernel values

% grep -i CONFIG_PM .config
CONFIG_PM=y
CONFIG_PM_DEBUG=y
CONFIG_PM_STD_PARTITION="/dev/hda2"

/sys/power% cat disk
shutdown
/sys/power% cat state
standby mem disk

To suspend i do

echo -n disk >/sys/power/state

Thanks for any more suggestions

Hi!

There's no pmdisk in -rc3.

swsusp in -rc3 should support apm.

Check your .config to see if it is enabled, and make sure you have
resume= on command line. If it still fails, mail me dmesg of failed
attempt.
