ACPI suspend to RAM weirdness

ACPI suspend to RAM weirdness

[Jason Munro]

Hello all,
   I can sucessfully suspend with 'echo 3 > /proc/acpi/sleep' on my Toshiba
Satellite 1410-S173. It also wakes up fine, except after waking it jumps to
init 0 and shuts down. It's been this way with every kernel I have tried
since 2.6.4. I know it worked with 2.6.1 but I'm not sure exactly at what
point between that and 2.6.4 it changed, or even if this is a userspace or
kernel issue. Yesterday I tried with 2.6.6-rc2 and rc2-mm1 and it still
behaves the same.

Any suggestions?

tia,

Kill acpid before suspending.
For some reason ACPI does not "clear" the power button event generated
when you press it to return from suspend :)

Same problem here with an Toshiba Sattelite Pro 6100.

There is some tracking done on this bug at:

We have some event/wakeup GPE weirdness lately.
You might try working around it by shutting down acpid
before you suspend -- it may be processing your wakeup
power button event as a signal to shut down.

It worked perfectly :)
