Mint 17.3 boot freeze when hardware config changes?

[pisior]

Mint 17.3, Radeon HD 4890, i5 750, Intel DP55WB, ssd disk
System works well, no problems at all when it is on. But there are problems with booting. Usually it hangs showing blank screen with cursor in the left upper corner, or sometimes it hangs in later stage of booting (like on the screenshot). At first I assumed this is the graphic card issue and tried to fix it by add radeon.modeset=0 in grub. No effect. But later I noticed some corelation between configuration of last succesfull boot and new boot. If something in hardware configuration has changed since last boot, new boot will freeze. Example:
- last boot with 2 monitors on, new boot with 1 monitor on and one off will hang booting; in this case using 2 monitors on boot will successfully start the system.
- last boot with no network cable connected, new boot with network cable on, will hang bootting; when I disconnected network cable, Mint started with no problems. Look at screenshot - this is the moment of stop booting:

It seems that freeze depends on hardware configuration changes.

Can you help me fix this problem please?

In a terminal, enter the command:

Code: Select all

dmesg >> $HOME/Documents/dmesg.txt

Then open /Documents/dmesg.txt in your text editor. It will list what is happening at boot by the second so that you can locate where the hang is.

Do you get the same type of delay when booting the live Mint DVD?

Thank you for reply

1. Yes, live dvd (LM 17.3 64bit - the same like installed one) hangs too.
2. each time after system hangs, last line of demsg is:
[ 395.327799] sound hdaudioC1D0: HDMI ATI/AMD: no speaker allocation for ELD

-edit-
Yesterday I switched computer off with 2 screens active (hdmi and dvi). Today Mint hanged multiple times at the same line, showed on picture above (mode: #0 CPUs: #1). There was no way to boot the system. Switching on and off second monitor gave no result.

I changed BIOS CPU settings to 1 core active only. Mint boots very well on CPU with one core.
Look at demsg. It shows i7 instead of i5. Does it have any meaning?
