Yesterday, I tried to install CentOS 7.0 with the default Gnome 3.8 on a Intel NUC (DN2820FYKH, a low cost Celeron, here are the specs : http://www.intel.com/content/www/us/en/nuc/nuc-board-dn2820fykh.html). EDIT : I previously updated the NUC with the latest BIOS released the 05/13/2014, here https://downloadcenter.intel.com/SearchResult.aspx?lang=&ProductID=3782&ProdId=3782
I wasn't able to boot with the system with default kernel. After selecting the kernel on the grub menu, it immediately displays an error message [0.000000] tsc : Fast TSC calibration failed (which seems pretty much harmless from what I read on various forums) and a gray screen. Then, it hangs there indefinitely.
I could only boot Centos 7.0 on rescue mode. This time, it displayed the same calibration error message followed by this :
Code: Select all
*ERROR* Cannot initialize the agpgart module.
DRM: Fill_in_dev failed.
Then, it seemed to boot normally (I didn't see any errors in the boot.log). But, the whole system was very slow (especially compared with Fedora 20, which runs like a breeze on the same NUC with Gnome 3.10). I updated CentOS and rebooted but the issue persist.
It makes me wonder :
Is it a kernel issue ? Maybe the 3.10 kernel doesn't really support well the Bay Trail processors.
Or maybe its the Mesa driver fault ?
In both cases, it doesn't seems I can do much about it... Using different kernels or Intel drivers would probably ruin the whole stability advantage of using CentOS...
Has somebody succeeded in running CentOS 7.0 on a similar NUC ?
