Ubuntu 12.04 on Lenovo W520 with Intel RAID - don't waste your time

I think Ubuntu 12.04 is a big failure. It's unstable and buggy to the point where I think it just deserves rm -rf /*. I can't believe an unstable product like this is labelled as "LTS". I've been reading Ubuntu forum and found too many issues regarding lockups in this version. Separating the install into "desktop","alternate","server" just so that it fits into a CD doesn't make sense. This is 2012 and even on the racks there's DVD-ROM. The price difference between CD-ROM and DVD-ROM is so minimal it is just not worth it to separate the contents. Also, regarding the lockups, don't blame it on X Window - it's the whole package that matters. Last year when I tried 11.04, the partitioning tool in the installer never work properly (GPT, MBR issues) I had to use Redhat's Anaconda installer to partition it and then use Ubuntu. A year later it's still the same and it's even buggier!!

The installer also failed to detect my RAID and yet it said "Installation is complete". This release is so bad it makes Windows Vista looks so much better. If I want a buggy, unstable OS with nice eye candy, I'd install Windows ME or Vista, not Linux.

On the other hand, Oracle VM Server (derived from Redhat Linux) installed just fine on Lenovo W520 and it perfectly detected the RAID configuration and everything was smooth sailing with no lockup whatsoever.



Executing 'grub-install' /dev/mapper/isw_BLABLABLA failed. This is a fatal error. Then it said "Installation is complete. You need to restart the computer in order to use the new installation.

FAIL.
