Default Kernel OOPS / panics with Matt Price's rtl8192se-dkms driver on Asus EEE 1201N, Lucid Lynx 10.04

Hi,

To get the wireless working, I used the unofficial package that can be
found here:
https://launchpad.net/~matt-price/+archive/mattprice

as advised on the EEE forums.

The driver works very well, however I got random freezes here and there,
especially when using the network consistently. Funnily enough, they
seem to happen when the *ethernet* connection is being used, however I
admit I haven't used wireless so much to get a statistic.

I get also kernel oopses here and there which can be related to the
freezes. Below is an example oops log, from dmesg:
