Comment 11 for bug 130221

Looking at hald/util.c I can see at least a couple of places that might be responsible for this. Back in 2005 there was a patch to fix these reports called "hal-fix-seqfault_if_addon_missing.diff". Unfortunately hald's util.c has been reworked since then and the issues that patch addressed may have been inadvertently not been handled by the new code.

To get an idea of which device is causing the issue we need a couple of log files from a clean start. The files are:

/var/log/messages
/var/log/debug
/var/log/dmesg

Before restarting you should remove or delete the first two existing log files so they will be freshly created at boot-time (dmesg is recreated each start). The reason for these two is:

1) both have timestamps that can be matched to events
2) debug inadvertently contains reports of hal_device_added/removed events through NetworkManager's debug-logging.

Once you've captured the error in the logs please put them together and attach them to a comment:

$ tar -czvf hald-addon-acpi-debug-logs.tar.gz /var/log/dmesg /var/log/messages /var/log/debug
