[ 46.064323] kernel BUG at
/tmp/makepackage/PACKAGES/linux/source/mm/slub.c:3440!
[ 46.064539] invalid opcode: 0000 [#1] SMP
[ 46.064722] CPU 1
An "opcode" is an operation code... it is a part of the "word" that arrives
at the processor at each clock cicle -- that word usually has 32 or 64 bits.
The other parts of it are the operands with which the CPU will do the
operation represented in that code. As for SMP:

It's probably a bug in your kernel's CPU architecture implementation. Try to
use Linux-libre 3.5 by installing "linux-generic-lts-belenos" from Trisquel
repos; or use a more up-to-date version from http://jxself.org/linux-libre or
