[Bug 532733] Re: apt/dpkg in qemu-system-arm hangs if a big task is installed

[Zygmunt Krynicki]

Hi

I can reproduce this each time by running netboot installer using the
versatile kernel:

#!/bin/sh
qemu-img create -f qcow2 sda.qcow2 16G
gdb --args qemu-system-arm -M versatilepb -m 256 -cpu cortex-a8 -kernel vmlinuz -initrd initrd.gz -hda sda.qcow2 -append "mem=256M"


Here is the backtrace:
