I've tried Ubuntu, Linux Mint and Debian, even though all have worked great for me I'm keeping with Ubuntu, I tested 12.04, 12.10 and even 13.04. The 12.04 LTS is the one I work with.

There's one issue persisting in the three distros I've tested, sometimes at random occasions the boot fails, after GRUB, it shows only a _ as prompt and it remains indefinitely, I've let pass up to an hour, and best I could do was to wait for a while and try again until I get it to load.

Everytime this happens and I've selected recovery mode I get logs like these:

Once I got this output enter image description here

So, I blame the last line:

[ 0. .... ]Booting Node 0, Processors #1

to be the issue, all first log lines appear continuously but it'll stop then.

I already updated BIOS, but there's something I think it might be the issue and that's the Hyperthreading, I had disabled it after BIOS update and it stopped happening, now I enabled it for installing a 64 bits OS in VMWare Player and it happened again.

I googled and I've not really found a solution.

Seems a known [problem][1], related to a BIOS incompatibility, apparently updating it did the trick. [1]: ubuntuforums.org/showthread.php?t=1706348 – vfbsilva Aug 25 '13 at 6:56

What do you mean? – diegoaguilar Aug 25 '13 at 7:13

add nosmp option to kernel in your grub

Can you explain what that would be for? To be honest with the most recent kernels I got rid of the problem. – diegoaguilar Jun 7 '14 at 8:08
