sleep sends my laptop into a suspend/resume loop

[Bas Zoetekouw]

The default sleep.sh/resume.sh scripts put my laptop into a sleep/resume loop as soon as I suspend for the first time. After that, it'll resume nicely, but go into suspend mode right away, with no time for me to kill acpid or so.

It seems it is a race issue with the 5 seconds timeout before /var/lock/acpisleep is removed. If I increase the timeout to 10s, it works fine, but I guess that doesn't fix the real problem: acpid processes some phantom powerbutton event as soon as the resume.sh script exists. Isn't there some way perhaps to clear the acpi event queue during suspend/resume script processing? Maybe acpid itself should be stopped/restarted by the scripts?

first you should tell us what is your laptop...

Oops, sorry. It's an HP Compaq nc6120

I've increase the sleep delay to 10seconds in my local copy.

acpi-support (0.69) unstable; urgency=low

  * Increase 'acpisleep' lock-out delay from 5 seconds to 10seconds. [Malone: #35108]

Uh, where exactly is this fixed? Breezy has acpi-support version 0.73, and that still has the 5 second delay rather than 10 seconds.

[Bas Zoetekouw (baszoetekouw)]

uh sorry, I meant Dapper of course, not breezy.

Also, just changing the timeout to 10 seconds doesn't seem to help much, as /etc/acpi/sleep.sh doesn't seem to check for the lock file any more.
Adding a "test -e /var/lock/acpisleep && exit" to sleep.sh (and increasing the timeout to 10s) does solve the problem.
