Hi all,
I upgraded from 9.10, latest patch status, to 10.04 via update-manager.
It's a virtual machine, powered by VMware Workstations 7.1 hosted on a
Dell Inspiron 6400 running Ubuntu 10.04.
- Upgrade procedure runs flawless, except that the upgrade procedure didn't
recognize that there is already Grub2 installed. After
I selected "Keep current configuration...", I got a message that it could be
that the actual grub configuration won't be able to
handle the installation. However the system was booting fine - no errors etc.
- I tried to recompile the VMware Tools, but there I got the first time the
message regarding to the mtrr.
- I re-installed the VMware Tools (that's without compiling) and it seems that
the VMware Tools since then working fine.
- But in /var/log/dmesg I found this:
[ 0.000000] MTRR variable ranges enabled:

- Configured RAM is 1024MB - The system is showing 1002MB.
- I can't noticed any problems while the system is in use.
- I didn't tried to re-compile the VMware tools yet, but I will do so and I
will check out the upstream kernel, but 1st I have to
read the web page. ;-)
As soon as I have news, I will come back and document it.
Regards,
Wolf
