some errors - not sure

[david]

hi all
im running fc2 on amd64 on msi k8tm, kernel 2.6.7-1.492

i get this message when i open gedit to edit files from root
this may not be the correct way to open them, but its the only way i
know how too:

[root at localhost dovik]# gedit /etc/yum.conf
 
(gedit:4168): GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols
specified are supported and host-based authentication failed.

gedit still opens and i can edit and save the changes, but why the
error?

next from /var/log/messages:
this first section is on shutdown
 
Jul 24 01:08:34 localhost kernel: ******* Your BIOS seems to not contain
a fix for K8 errata #93
Jul 24 01:08:34 localhost kernel: ******* Working around it, but it may
cause SEGVs or burn power.
Jul 24 01:08:34 localhost kernel: ******* Please consider a BIOS update.
Jul 24 01:08:34 localhost kernel: ******* Disabling USB legacy in the
BIOS may also help.

i will check to see if usb legacy is enabled on next boot

not sure on this one;

OAFIID:BrokenNoType:20000808 has a NULL type
Jul 24 01:09:15 localhost bonobo-activation-server (dovik-3995): invalid
character '#' in iid
'OAFIID:This#!!%$iid%^$%_|~!OAFIID_ContainsBadChars'

or this one;

48k fixed sample rate.
Jul 24 01:09:17 localhost kernel:          Please try dxs_support=1 or
dxs_support=4 option
Jul 24 01:09:17 localhost kernel:          and report if it works on
your machine.
