acpid: can't open /proc/acpi/event

[Rkimber]

Once a week I get a message:-

/etc/cron.daily/logrotate:
acpid: can't open /proc/acpi/event: Device or resource busy
error: error running postrotate script for /var/log/acpid
run-parts: /etc/cron.daily/logrotate exited with return code 1

If I try to open /proc/acpi/event I get

/proc/acpi/event: Device or resource busy

lsof /proc/acpi/event gives:-

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
hald-addo 4669 haldaemon 4r REG 0,3 0 4026532108 /proc/acpi/event

I am using Dapper on dual opteron.
2.6.15-25-amd64-k8

Same message for me. acpid refuses to upgrade:

Paramétrage de acpid (1.0.4-5ubuntu1) ...

Same during a dist-upgrade to Edgy. acpid held up ubuntu-desktop saying acpid: can't open /proc/acpi/event.

Running /etc/init.d/acpid stop and then /etc/init.d/acpid start returned the same message. Don't know if this is regular or not, but sudoer and root can't delete /proc/acpi/event, even after it is 'stopped'. A cat of /proc/acpi/event shows that it doesn't change.

Was able to bypass the error by killing the acpi process.

I have what I think is a related problem.

I also got messages like those above when I upgraded to Edgy. I found a message posted about this (sorry, forgot where) which suggested doing this:

sudo /etc/init.d/acpid stop
sudo killall hald

then finish the install.

this worked. but I keep getting messages about /proc/acpi/event being busy. They seem to be solvable
when I do this:

sudo /etc/init.d/acpid stop
sudo killall hald
sudo /etc/init.d/acpid restart

this works until the next x session starts - also I don't know
what this is doing to hald's functionality.

good luck

Thank you for your bug report. Do you still have this issue with the latest release of Ubuntu ?

[ketan (ketanmd)]

No, I believe this bug is now fixed.
I'm running Feisty and it is fine.

thanks for the follow up.

Ok, Thank you. I'm marking this as fixed.

I believe this bug to have been mistakenly filed against sysvinit. Since a fix has been released to acpid, marking this bug under sysvinit as Invalid.

[ketan (ketanmd)]

Hi,

I thought this bug had been marked as fixed in 2007.

[message from Jerome Guelfucci about bug 51591 on Sun Jun 10, 2007]

Ok, Thank you. I'm marking this as fixed.

** Changed in: acpid (Ubuntu)
      Status: Needs Info => Fix Released

Anyway, I've long seen what appears to be fixed behaviour (since Feisty...)

thanks for the follow up though.
