I'm very new to ubuntu. I try to change my desktop for Ubuntu because I'm bored with windows 7 and I'm try to learn about ubuntu. First I'm try Ubuntu 12.04 LTS 64bit. After i choose "Instal ubuntu" my computer restart and I getting error "Hyper Transport Synch Flood Error".

I change my instal from CD to USB bootable device, disable HPET and all integrated device, underclock my cpu, increase the voltage, but i'm still get the error. So I'm trying the older version 10.7, But I'm getting the same error.

When my friend lend his VGA (AMD HD 4850), I can instal it without any error. After finish installing, I swap to my AMD HD 3870, It can't boot into ubuntu again. When I change into 4850 again, it can boot normally

I read the kernel support AMD 3870, it has the same kernel support with 4850 so i don't think it's kernel fault in this problem.

I don't know to solve this problem, maybe someone can help me with this problem.... Thanks in advance...

ps: when I try to install openSUSE 10.3 I get no error, But when I try openSUSE 12.2 I get the same error as ubuntu.

my computer spec :

AMD phenom II 550 MSI 770-G45 Memory GSKILL DDR3 2x4gb AMD Radeon 3870 Seagate 250GB Seasonic GOLD X 650Watt

I advise you to take down the Ubuntu 12.04 LTS and install 10.04, since I also have a ATI Radeon HD 3870 and I'm tired all the time to configure the driver. I got angry and now downloading Ubuntu 10.04 LTS.

P.S. On Ubuntu 10.04 LTS more manuals than 12.04 :D

P.P.S. Sorry if I write with mistakes. I am Russian, and understand very little English, so I used Google.

@Handoko Ubuntu 10.04 LTS is going to better than 12.04. But the problem with drivers is the same - after installing AMD Catalyst start lags. I created a question on this issue. I hope me can help. And at the expense of your problem, I do not know, because I also recently started using Ubuntu. – Skuyall Nov 28 '12 at 8:52
