Continue the investigation. I fixed the Virtualbox problem, it turns out that PAE kernel is running but i686 Virtualbox kmod is installed. A re-install fixed the problem.

Last but not least, I found the root cause to the x86_64 unstable problem. I was mounting a NFS mount on /tmp, which caused a write error that cascade to GNOME.

[update] The sound device missing problem was fixed after recent kernel update to 2.6.33.5-112

After migrated all data from T60, the new T410s is open for business. I first run an yum update and install software I need. It's trivial work, but time consuming. Sometimes I just wish upgrade work, which I never attempt.

In general, all basic functions like X, mouse, trackpad (w/ scrolling), wireless are working. I tested a few other functions like suspend and webcam, both working. I'm still yet to test ethernet, fingerprint scanner, eSATA, HDMI, and DVD burner.

So far, I noticed sound (missing device) and compiz (crashed after a while) are not working. In addition, some kernel modules are missing with Virtualbox.

On the other hand, the new T410s is quite an improvement over my T60; The CPU is running pretty cool at about 38 degree, and the build is much solid (but there is still some flex).

Downloaded F13 the day it was released and burned it on DVD. I got both the i386 and x86_64 version. I recently bought a Lenovo T410s w/ a Intel Core 5 CPU, so I thought I would give the x86_64 version a spin first.

But to my disappointment, it's very unstable. I'm getting freeze up left and right (but this one might be related to Compiz...), and program crashed when starts. So, I switch back to i386 version.
