I'm currently on Lenovo G580. I managed myself a dual-boot system with Windows 8.1 and Ubuntu 16.04 LTS installed in EFI mode (because my laptop refuses to carry them both not in EFI).
For some time my system works fine, however, after a few days Ubuntu suddenly breaks down. Firsly it gives me
Support for core revisions 0x17 and 0x18 disabled by module param allhwsupport=0. Try b43.allhwsupport=1
Using this forum I figured it out that the problem is in wifi adapter or smth and people usualy skip this warning if their wifi works fine. Although I have no problems with wifi this message do not allow me to log in. I tried to fix it as it were suggested here. System launched and after a reboot crashed again with:

This error-message repeats and it ends like this:

The thing is, that it is not dificult for me to reinstall the system. But this problem is arising in a few days after every reinstallation. No matter if I tried to fix that problem with wifi or not. While Windows works perfectly.
I'm not an advanced user of Linux and I need it only to work with programms for quantumn chemistry calculations (ABINIT). And that is exactly what I do. The only thing I do after installation is compiling ABINIT and installing some libraries to Python (numpy, scipy, simpy, matplotlib and ASE). But Ubuntu continues to crash without any reason. The last of my efforts to reinstall it ended up with a crash after only 1 reboot. Previous one stood for several weeks and dozens of reboots. The one before it maybe for 1 or 2 reboots. And so on ... This is quite annoying.
After searching through the topics I thought that the reason might be in hardware. Model of my HDD is Seagate ST1000LM024 HN-M101MBB (SATA) and sysmboard LENOVO INVALID (U3E1) (actually, I doubt that INVALID - means something good).
I would appreciate any recomendations or advices. How can I achive stable work of dual Windows/Ubuntu in my case? What is the problem so far? If the problem is with hardware - maybe I should bring it to service center and ask them to fix/change systemboard/HDD or the problem might be in software?
