Yes, but it runs on a core i5 2500, which is not really different from a
core i7. Anyway i don't think the CPU really plays a role there, but
really more kernel version, or the environment. For example have you
changed /etc/security/limits.conf ? Limiting the maximum number of
processes per user will cause this kind of issue.
After spending some hours trying to get a PXE server with a full Debian
installation going,
I remembered that I had an external hard disk with Debian Wheezy amd64
installed.

The build succeeded with this configuration.
I also noticed that there were several occurrences of
[Hardware Error]: Machine check events logged
in /var/log/messages
Also, the Nouveau driver loaded.

=============================================
When I connected the hard drive to my spanking new Samsung NP-RF711-S07UK
and ran the tests, they failed in the same place, indicating a driver or
hardware problem.
Also of note, the specifications for this machine seem to be a bit fluid -
mine has 8G ram, a 1TB hard disk (which I swapped out for a
Seagate Momentus XT ST750LX003 2.5" internal hard drive - 750 GB + 8 GB
SSD memory),
a i7-2670QM processor and 1G dedicated video memory, unlike the specs on
Samsungs
own web site.
The place I bought it from some weeks ago no longer lists it, but I
don't know if that's
a cause for concern.
Regards,
Philip
