Upgrading Archlinux

Few days ago I decided to upgrade my Archlinux OS. This is first time I issue the pacman Syu command. Since it is already some time from fresh install, the required file is big enough: around 371 MB.

After completing the process, I restart the machine and struck with kernel panic message. It says that the system cannot mount root directory to the unknown device.
Googling for awhile, I pointed myself to get some info on mkinitcpio section of Archlinux wiki. The wiki told me that I have to edit my GRUB menu. Apparently it fails to load the correct image, i.e /boot/kernel26.img or /boot/kernel26-fallback.img.

I did not realize that I have to edit my Solaris GRUB, not Arch, since the machine uses Solaris GRUB which is directly load the required image of Arch kernel.

So everything goes find, but the Xorg server. It froze when I run startx.
Quick search on Xorg.0.log shows that my ATI driver does not support my chipset series: Radeon 9250. So I reconfigure again the Xorg, and be able to login into graphical environment.

Last thing to tweak is the screen resolution: max resolution only 1024x768, while my SyncMaster 793 can handle 1280x1024 at 65Hz. From online modeline generator, I found that the horizontal refresh rate has to be corrected as per my monitor specs. 30-70kHz.

Finally I can enjoy my newly upgraded Archlinux...:))
