[Virtual-pkg-base-maintainers] Bug#705124: base: Filesystem corruption issue

[Anthony Sheetz]

Package: base
Severity: critical
Tags: lfs
Justification: breaks the whole system

Dear Maintainer,
We have discovered a bug which results in corrupted logical volumes, causing xen virtual machines
to be unable to boot.
We have experienced this bug on two different laptops - Lenovo Thinkpad T430, Asus G55V

Steps to reproduce:
Install Debian Testing from Netinstall CD, amd64.
Choose LVM and Full Disk Encryption, with a separate /home
Resize /home to be 80GB
Install openswan, connect to remote network
Install xen
Set up a virtual machine with Debian Stable using logical volumes as the backing store.
	fs: ext3
	network: NAT
transfer a large (multigigabyte) file from a remote server over the internet to the virtual machine

Expected behavior: File transfers fine, md5sum agrees with remote system
Observed behavior: md5sum never matches, done enough times, the ext3 fs becomes corrupted.

Have some saved log files to include - will attempt to do so once this ticket is filed.

Have tried using a second machine as a network tunnel to the remote server, and still got an invalid checksum.
Have tried scp and rsync, both fail similarly.
Have tried Stable Dom0 with Stable DomU, file transfers succesfully.
Files transfered between Dom0 and DomU transfer fine.
Files transfered from a computer on the local network transfer succesfully.
Bug occurs on two different laptops in the same way.
