I am trying to install 64 bit Ubuntu 13.04 on a new system. I can only run Ubuntu with "acpi=off" option. This applies to both attempt to run Live USB and installed system. If I do not give "acpi=off" the system hangs after a few seconds to a minutes of starting up. For the moment it hangs syslog does not contain any ACPI related messages. While booting with ACPI on I am seeing the following error messages:

ACPI Exception: AE_BAD_PARAMETER, Thread 849680192 could not acquire Mutex 0x1

As suggested in https://wiki.ubuntu.com/DebuggingACPI I tried “acpi=ht” and I see the same symptoms as without any acpi options. As it works with “acpi=off” and fails with “acpi=ht” I assume that the issue is in the ACPI table parsing code itself, or perhaps the SMP code. I am not sure what to do next.

I am also not sure what are consequences of disabling ACPI. I understand that I can not manage power but will it also affect my performance? I assume so as apparently even hyperthreading does not work (I checked that it does not).

Any advice will be highly appreciated. Also if somebody can point me to a professional support that might be able to help me I would be happy to go for it.

My System: Clevo P570WM SMBIOS 2.7 present. BIOS: Vendor: American Megatrends Inc. Version: 4.6.5 Release Date: 01/21/2013

Linux 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Cheers, Michael

See if they have an updated bios to install, otherwise you're probably going to need to replace the motherboard with a different one. –  psusi Jun 17 '13 at 21:55
