Happy new year!!! to all.
Please help me if you can with the following issue.
I have bought specially for QubesOS a Lenovo Thinkpad T series laptop as recommended. I have targeted a T530 and I ended up with:
Lenovo Thinkpad T560 (20FJS03M00), Bios N1KET50W (1.37) 11/20/2020, I7 6600U Processor, 32 GB RAM, 500 SSD Samsung EVO and with integrated Intel HD Graphics 520 / Skylake-U GT2
Unfortunately after installation of Qubes OS the system is just freezing after short time I’m starting it.
The time is randomly, sometimes take hours other times minutes until is freezing.
I have tested also with other Linux distributions (Ubuntu 20.04.1 LTS , Tails OS bootable usb). Both of them are behaving in the same way “system is freezing after a period of time”. Ubuntu is more stable, Tails is freezing very quickly.
When it is freezing any key I press or combination is not showing any reaction.
I have tested the hardware (cpu, ram, gpu) with various tools (occt, metestx86…etc).
The laptop is working fine with Windows 10, not freezing no error.
I understand by searching on internet that there is an issue with the kernel or latest kernels and the Skylake Intel Integrated Graphics.
I did not spend to much time to search for an workaround on Ubuntu or Tails (even if on Tails I have tried few things which did not worked), this is because my target for this laptop was Qubes OS.
I have tried both stable 4.0.3 and test vesion 4.0.4-rc1 both with the same behavior.
I have also a ThinkPad T420 which works fine with QubesOS from this point of view but this one does not meet the Qubes OS requirements and I have other issues with that one. Therefore I have invested in this T560 which I cant use it properly for the moment.
Please help me if you have any idea of how can I solve this freezing issue. I don’t know where to start from since it is using Xen …
Thank you in advanced.
