After install fedora 17 into my friend computer, My desktop gets your turn.
I follow my classic fedora installation method.
- Download install DVD x86_64 version iso image.
- Burn a blank DVD
- Boot my computer from the DVD
these are my normal steps but my boot DVD shoa lot of errors like:
SQUASHFS error: Unable to read page, block xxxxxxxF, size xxxF
I read some info from forums and they say that the problem was with the dvd, Because after install fedora in my desktop I was installed Hasefroch 7 and burned Fedora ISO in the same computer.
After Downloaded Sha256 for windows and check that I have the correct image, i go to bed and leave the computer checking a new recorder DVD.
When I get up I observer tat new DVD has errors too, so i decided to download a live cd iso and try with live CD, this method works and i could install fedora but i saw a small number of errors but it was thinking the live cd too small for support everything. so i decide install my system from the live cd hopping that errors disappears at first boot.
After install a bad behavior appear in the screen and system appears to frozen in moments with unexpected X restarts. I decide to check running process using top et voila. My Phenom computer only has one processor working 🙁 . After that I remember that when change the hard disk some wires from the pow source stopped the CPU fan for a moment, 20 secs approx, a disaster has coming i burn my cpu and need to buy a new processor, but when i reboot on haseforch saw four cores working, that not was a CPU problem so I check the dmesg output.

I try changing kernel boot parameters without acpi with NOACPI and a lot of things and every time that my computer reboot my Linux only show one core.
Finally i found the guilty element it doesn’t was the CPU it was the motherboard
I update the bios using the last version but it doesn’t work, finally I download a BIOS beta version , mb_bios_ga-ma785gm-us2h_f12a, from gigabyte web page and it works.

Now all the cores are available. Screen doesn’t works yet and I’m downloading a new DVD copy because i don’t like liveCD install.
