Comment 350 for bug 263555

Currently, we're busy testing the patches we've put into beta2. These
are mostly patches from intel, also posted upstream on LKML

On beta1, we're able to reproduce the issue pretty reliably by simply booting
into runlevel 3, and shutdown the machine 1 minute later. The problem will
usually show up within 3-20 reboots. With beta2, we have so far run 350
reboots or more without hitting the problem.

We're currently still discussing with Intel and LKML what the cause of the
problem may be. We're chasing a number of leads, but it seems at least
one of the patches we have so far is effective in stopping the corruption
from happening.
