System boot too slow - LM14

[kimented]

Hello,

My laptop boot is very slow, I never had this before. When I boot with nosplash, the boot freeze one minute at this message:

Code: Select all

 * Starting CPU interrupts balancing daemon[154G[ OK ]

OS: Linux Mint 14 Mate 32bits
CPU: Intel DualCore i686
GPU: VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Thank you for your help.

You can see my bootchart attached to this post.

As you can see from your bootgraph your hard disk is completely stressed out for over a minute (high wait I/O means processes are waiting for the hard disk to complete their requests). It can't load the files fast enough and so the boot process is dragged to a crawl as everything is waiting for the hard disk to just do its job for once (you should fire it from its job it BTW, get a SSD). That may however be an indication of the hard disk having problems. Suggest you install gnome-disk-utility and then run Disk Utility from the menu and do a read benchmark for your hard disk, and look at the SMART information. Check that everything is okay with the hard disk before you try anything else.

When did you download and install Linux Mint 14? Last day of November the ISOs for Linux Mint 14 were refreshed because previously there had been an issue with bad performance in Intel GPUs. See this announcement: http://blog.linuxmint.com/?p=2234. That was fixed in MDM version 1.0.8, which you should have on your system if you are up to date. You can check easy on the terminal with the following command. You should have MDM version "1.0.8+nadia".

Code: Select all

dpkg -l mdm

Aside from that, you can disable some services you may not need and perhaps that will help (less files to load). Some ideas for that here, also see the posts linked from that post, http://forums.linuxmint.com/viewtopic.p ... 77#p600177.

Not sure if it will put much of a dent into it, but you could remove the VirtualBox guest additions. You only need those when you are running Linux Mint inside a virtual machine. You can safely remove then if you are running on metal.

Code: Select all

sudo apt-get --purge autoremove virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

Ok, it seems my HD will die... It's just strange I have no problem when the system is totally launched.

Read Error Rate: 86060705 -> this number don't seems to change
Seek Error Rate: 47 554 334 932 -> this number increases fast

Thank you for your help.

Ouch That's bad news, I had hoped it to be something else. At least you caught it in time and can back up your personal documents before it breaks further.
