Hi,
I have a server with Supermicro X7DVL-3 (P9) motherboard, 16G ECC RAM and LSI SAS 1068e RAID controller. I installed CentOS 6.5 64bit on the machine without any problems, but after following the Xen setup steps at
http://wiki.centos.org/HowTos/Xen/Xen4QuickStart
which installed me the kernel 3.10.32-11.el6.centos.alt.x86_64, I encountered a problem: After "Starting certmonger [OK]" the screen went black and the system became unresponsive: keyboard was not working (NumLock did not respond) and SSH was not responding either. After first lockup I increased dom0 max mem to 2G, but rebooting after that produced the same result. The strange thing is, that after a third reboot everything worked ok: screen went black for a moment after "Staring certmonger [OK]" but after that the graphical login screen appeared and I could use the system normally. The fourth reboot went ok as well.
Any ideas what could cause this kind of behaviour?
Regards, Peter
