[Solved ]Not tainted 4.5.1-1-ARCH and Failed to start Journal Service.

Hi i'm new to Arch Linux, i'm trying to install it following the wiki.
Every 3 minutes , or so, i'm having this error:

[240.285293] INFO: task kworker/u8:3:102 blocked for more than 120 seconds.
[240.285293] Not tainted 4.5.1-1-ARCH #1
[240.285293] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Is something wrong? Is this normal?

Now i'm getting this:

[2174.021888] systemd[1]: Failed to start Journal Service. 

Thanks for your advice.

Solution:
It is a bug whit AMD cpu and kernel 4.5.
I make a booteable usb with an older version on archiso (2016.03.01) and installed it.
After that I followed this

Re: [Solved ]Not tainted 4.5.1-1-ARCH and Failed to start Journal Service.

This warning basically says that you have some unusually slow I/O device. The real info here is "task $foo blocked for more than 120 seconds", not the "not tainted" part.

What are you trying to install Arch Linux on? Some older SD card perhaps?

If your target device is indeed very slow, then you can ignore this warning. But if you're installing on a regular SSD, for example, connected by SATA, then this warning should not show up.

I'm trying to install it in a laptop , it is not too old...
Then I should not worry about the message?

What Vain said. This may not be what you want to hear, but you can effectively ignore this error. In fact,

[240.285293] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

The error gives you a way to disable it. Run that command in another TTY (CTRL+ALT+F_) and you should be good to go.

Re: [Solved ]Not tainted 4.5.1-1-ARCH and Failed to start Journal Service.

I'd probably ignore the warning for now, but I'd also check the output of smart for the drive in question. The warning you're seeing right now could be caused by a failing drive.

Also watch out for real I/O errors. Regularly check your log files, i.e. run `dmesg` or have a look at systemd's journal. I/O errors can look something like this:

[ 4859.199016] blk_update_request: I/O error, dev sdc, sector 0
[ 4859.199019] Buffer I/O error on dev sdc, logical block 0, async page read

However, if you're getting those, it might already be too late.

By the way, I'm seeing your warning regularly when I copy large amounts of data to an external USB hard drive -- that's an example of a "slow" device. I also see it on servers with waaaaaay too much load. The warning itself is usually harmless. Still, you should not get it when writing data to the hard drive of a modern laptop, hence the advice on checking your hardware.

Ok. I did the smart test and got no errors. I disabled the message, but now I'm getting :

 [2174.021888] systemd[1]: Failed to start Journal Service.
