Hi to all.
Seems to be a BIOS bug; ingredients :
+NUC DN2820FYKH
+SSD Kingston 60GB 450 MB/S SV300S37A/60G
+SO Centos 7.1 - July 2015
+ MEM Kingston 4GB KVR16LS11/4
+ BIOS version 050 and 051
No other USB devices are plugged into NUC.
I testing NUC doing a automatic reboot every 5 minutes.
After about one day max, the NUC reboot hang when bios display "Intel NUC", "press F2 ..." .
and CTR ALT CANC work for good reboot.
I start test with bios default setings and SO UEFI boot : reboot hang.
I tried other changes but without solving the problem :
+ Disabling Legacy boot when SO have UEFI boot
+ Disabling UEFY boot when SO have Legacy boot
+ Windows 8 mode and Windows 7 mode
+ disablig boot from network
+ disablig boot from network+optical
+ disablig post error messages
+ Bios 050 and some tests with 051
Seems that Bios sometime is unable to start with correct boot device/partition;
and the problems occurs more time when ssd boot disk is UEFI.
So now I'm testing NUC enabling only boot from SSD and disabling all other boot devices (USB,network,optical);
I hope at least that is ok;
hear news !
bye
