That is probably the issue then. In guaranteed mode, a process can not
have an address space larger than 32MB. apt-get probably wants more than
that. If you enable CONFIG_ARM_FCSE_MESSAGES and this is indeed your
issue, you should see some message in the kernel logs (FCSE: process
%u(%s) VM would exceed the 32MB limit)

If this is the case, check the stack-size with ulimit -s and see if it
is still 1MB.

Please no private mails.
