While I don't think this is the venue to report this stuff since you
asked, and since you are a person who helps fix things:

) I had these messages in dmesg (already sent to LKML)

EXT3-fs: mounted filesystem with ordered data mode.

2) (Not sent to LKML) Using 2.6.18-rt3 the machine hard crashes when
exiting from Gnome back to the gdm login screen. The machine is down
hard and would not even respond to ssh login attempts. I was using the
ati-driver-8.28.8 driver which is most likely the culprit. I was not
motivated enough though to muck around with my xorg.config files to
try the kernel's radeon driver. I hope to look at that this weekend.
If the radeon driver crashes I will send that info on to the LKML.
(And I suppose here since you want to see it!) ;-)

I am currently back to running 2.6.17-rt5.

Cheers,
Mark
