two other cases Re: [Bug 11721] after upgrade to 2.6.27 i cannot navigate

just as matter of information, two other cases similar to mine were
reported in ubuntu bug pages:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/272896
https://bugs.launchpad.net/ubuntu/+bug/285430
i originated the first one and gave Jarek's first solution:
tcp_sack=0
which worked for the two other users.

maybe they could be contacted in order to perform further tests in a
different environment.
