Summary:
SELinux is preventing /usr/sbin/acpid "read" access to device mouse1.
Detailed Description:
[acpid has a permissive type (apmd_t). This access was not denied.]
SELinux has denied acpid "read" access to device mouse1. mouse1 is mislabeled,
this device has the default label of the /dev directory, which should not
happen. All Character and/or Block Devices should have a label. You can attempt
to change the label of the file using restorecon -v 'mouse1'. If this device
remains labeled device_t, then this is a bug in SELinux policy. Please file a bg
report. If you look at the other similar devices labels, ls -lZ /dev/SIMILAR,
and find a type that would work for mouse1, you can use chcon -t SIMILAR_TYPE
'mouse1', If this fixes the problem, you can make this permanent by executing
semanage fcontext -a -t SIMILAR_TYPE 'mouse1' If the restorecon changes the
context, this indicates that the application that created the device, created it
without using SELinux APIs. If you can figure out which application created the
device, please file a bug report against this application.
Allowing Access:
Attempt restorecon -v 'mouse1' or chcon -t SIMILAR_TYPE 'mouse1'

Can you execute
# find /dev -name mouse1 -printf "%p %Z\n"
/dev/input/mouse1 system_u:object_r:mouse_device_t:s0
Does the mouse have the proper label on it?
Eric, this looks like one of those race conditions where the kernel creates a device and udev fixes the label, but some confined app apmd_t sees it first.
