The images are available here:
https://abf.io/platforms/rosa2014.1/pro ... ists/14366

I made some improvements there but do not know if they help in your case.

The images have received only minimal testing and may be buggy but at least one can see if the system boots in Live mode.
Working without any problem. Actually I am writing this from live session.

Good. So some of the differences in the kernel configs might be the reason. Thanks for the info.

I understand. Still, in case of ROSA, it helps a lot if the issues a reported to our Bugzilla in addition to the forums. Even if you do not know whether the issue is known. This is because some important bugs in ROSA, like this one, can be overlooked by the maintainers if the bugs do not make it to Bugzilla. The stream of bugs that get there is not very intense, so we will just close some as duplicates if these are for known problems.

Many maintainers of the key components of ROSA (like NicCo, like myself and others) are not currently employed by ROSA as a company. So it can be quite difficult to find time to monitor all the resources where the bugs can be reported, like this forum, the forums at rosalab.ru, the groups in the social networks, etc. This way, some bugs may remain unknown to us, which is not good.

Yes, hw-probe would collect many important pieces of information needed to fix the default kernel. It would help if you could boot the system with the kernel 4.1.15-nrj-desktop by NicCo (without nomodeset and such, of course) and use hw-probe to upload the data to us.

Thanks. If it still does not boot as is, you can try nomodeset xdriver=vesa, similar to what you did before. If the system boots in Live mode somehow, please use hw-probe there too to upload the logs from there.

Could you please check if the system boots OK with kernel 4.1.19 from this container: http://abf-downloads.rosalinux.ru/rosa2 ... n/release/ ?

To install the kernel, it is enough to run the following command:

Code: Select all

urpmi \
http://abf-downloads.rosalinux.ru/rosa2014.1/container/2627083/x86_64/main/release/kernel-nrj-desktop-4.1.19-2rosa-x86_64-1-1-rosa2014.1.x86_64.rpm \
http://abf-downloads.rosalinux.ru/rosa2014.1/container/2627083/x86_64/main/release/kernel-nrj-desktop-devel-4.1.19-2rosa-x86_64-1-1-rosa2014.1.x86_64.rpm
Alternatively, you can try the ISO image that already contains that kernel 4.1.19, in Live mode:
https://abf.io/platforms/rosa2014.1/pro ... ists/14663

I suspect CONFIG_INTEL_IOMMU_DEFAULT_ON option which was accidentally turned on in our kernels. It is known to have caused problems in the past. I turned it back off, let us see if it helps.

I made a few more changes there as well but the crash you saw was probably related to IOMMU, so that option is the first suspect.
