Linux kernel hangs on boot - DL180G6

[Andrea Spadaccini]

Hello everybody,
the Linux kernel (version 2.6.21.5-smp) hangs while booting on a shiny new HP DL180G6.

Here are the last boot messages shown by the kernel:

CPU: Physical Processor ID: 1
CPU: Processor Core ID: 0
Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#0
Compat vDSD mapped to ffffe080.
Checking 'hlt' instruction... OK.
Freeing SMP alternatives: 15k freed
ACPI: Core revision 20070126
CPU0: Intel(R) Xeon(R) CPU E5504 @ 2.80 GHz stepping 05
weird, boot CPU (#0) not listed by the BIOS.
Booting processor 1/16 eip 2080

Sorry for typos, I'm copying the log from a low-res picture.

I tried searching this forum and other resources, but I didn't find anything clear.

Can anyone please help me?

Thanks a lot,
Andrea

Try to boot with noapic option.

Thank you for the reply.

I tried booting with the noapic option, but it didn't work.

Any other suggestions?

Thanks,

Mhm... maybe try the acpi=off as for the kernel 2.6 it can sometimes help as well. If this will fail too, you can try to use it in combination with noapic option. Hope this will help to pass the boot sequence.

I just tried "noapic acpi=off pci=noacpi", but I get exactly the same error.

Thanks for your quick response.. Is there anything else that I could try?

Thanks again,
Andrea

It worked :D

I used the following parameters: "apm=off acpi=off noresume nosmp noapic maxcpus=0 edd=off".

Now I just have to find the option that let it work and understand if it's acceptable (nosmp would not be acceptable...).

Have a nice day, and thanks for your help!

The problem goes away with latest kernel (2.6.31.3) and some fiddling with the parameters (I changed the architecture to Xeon and changed other parameters that I forgot to write down).

Thanks again,
Andrea
