Comment 30 for bug 1035889

OK, I think I have narrowed it down. It seems that the problem exists in "v3.3.8-quantal" while it is fixed in "v3.4-rc1-precise" and "v3.4-precise". So I think any commit that fixed it should have been bewteen these two versions.
Even in the fixed kernels there are some messages(warnings/errors) in "/var/log/kern.log" after switching to 11Mbps, but then a hardware reset is requested and it is recovered. So it doesn't result in a freeze (at least based on what I understood from the messages).

If there is anything else I can do, just let me know.
