description of the problem

System works fine when powered on but when I reboot or either power off / on the machine hangs at the bios boot screen ( that with logo and F2 to enter setup ) and this happens sometime not every time ( randomly ). When it hang keyboard not work (ctrl+alt+canc not work) and to restart the system I need to power off and power on again or reset.

This is really a problem for example when I need to reboot the server from a remote station. I tried to update bios at the latest 1001 version but that not helped, tried to reset CMOS and loaded bios default settings, nothing changed it hangs sometime after a reboot or a power-on.

 

repro

Though I did not find an exact way to reproduce the problem I can easily reproduce by rebooting more times during hours ( sometime it restart correctly, sometime it hangs ).

 

question

Is there a well known solution to this problem ? and if so there will be some expected BIOS update in near future ?

I would like to use this cpu for the provided performance but I need also realiability and I can't suppose that the server hangs after a reboot so in the meanwhile I'm forced to downgrade the CPU to an A12 9800 hoping the problem doesn't occurs anymore.
