Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have installed ubuntu server on an HP G7 machine which is brand new.

Here is a picture of the frozen screen

For some reason when I rebooted from my office it got stuck at the screen above, sometimes its a black screen.

When that problem occurs I cannot do anything such as ping or ssh to it. I have to make a hard reset .

I have made a lot of researches and a few solutions suggest to pass the following parameters to the kernel :

warm =  Don’t set the cold reboot flag
cold = Set the cold reboot flag
bios = Reboot by jumping through the BIOS (only for X86_32)
smp = Reboot by executing reset on BSP or other CPU (only for X86_32)
triple = Force a triple fault (init)
kbd = Use the keyboard controller. cold reset (default)
acpi = Use the RESET_REG in the FADT
efi = Use efi reset_system runtime service
pci = Use the so-called “PCI reset register”, CF9
force = Avoid anything that could hang.

None of them fixed my issue, the server freezes from time to time. It is very strange please advice.

I've had this with G7 servers. Update all the firmware on the box.

I generally agree with running recent firmware everywhere if practical, but a reference to a HP support article or firmware release notes would help. (Answers should explain the "Why", not just the "How" -- cf. Press the Green Button Twice) –  voretaq7 Nov 13 '12 at 17:47
The first I did is to update my BIOS and firmware before installing any OS –  user200900 Nov 13 '12 at 17:51
@voretaq7 - If I had a reference I would give it, but I never bothered to look one up for this. Had the problem, upgraded firmware, problem went away :) –  Dennis Kaarsemaker Nov 13 '12 at 17:56
@DennisKaarsemaker Do you happen to know the revision that works at least? (theoretically that rev or any later rev should work so it makes it easier to see if the answer applies or not, though it sounds like this has already been tried so it may be a related-but-not-identical problem :) –  voretaq7 Nov 13 '12 at 18:02
iLO3 firmware 1.26, system rom I27, raid controller firmware 1.18. If it's a blade: upgrade the chassis firmware too (3.32 at least). –  Dennis Kaarsemaker Nov 13 '12 at 18:07
