selinux and udev problems after updates including latest kernel



 I got a flood of messages this morning after rebooting into the latest kernel 
2.6.23.1-10.fc7 #1 SMP  this morning. These had to with udev being denied 
whilst it was trying to do various things by Selinux:

**************************************************************************

Here's an example from SETroubleshooter:

Summary
    SELinux is preventing /sbin/udevd (udev_t) "relabelfrom" to scsi-
    SATA_WDC_WD5000YS-01_WD-WMANU1397503-part1 (device_t).

Detailed Description
    SELinux denied access requested by /sbin/udevd. It is not expected that 
this
    access is required by /sbin/udevd and this access may signal an intrusion
    attempt. It is also possible that the specific version or configuration of
    the application is causing it to require additional access.

Allowing Access
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for scsi-SATA_WDC_WD5000YS-01_WD-
    WMANU1397503-part1, restorecon -v scsi-SATA_WDC_WD5000YS-01_WD-
    WMANU1397503-part1 If this does not work, there is currently no automatic
    way to allow this access. Instead,  you can generate a local policy module
    to allow this access - see http://fedora.redhat.com/docs/selinux-faq-
    fc5/#id2961385 Or you can disable SELinux protection altogether. Disabling
    SELinux protection is not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

Is anyone else seeing anything like this? I probably got over 50 of these! The 
machine is up, and seems to be running normally, though I haven't done much 
beyond composing this email.
