Yes, I've seen the presence of "rtl8192" in the backtraces, but that does not mean much - it's just a kernel oops, which may or may not be related to the kernel panic that happens at some later point. The backtrace from the kernel panic itself would not appear in the dmesg, since all basic kernel functionality - including filesystem drivers - have stopped at that point.

That said, I'm under the impression that the rtl8192se driver is of rather bad quality (apart from unnecessarily noisy in the kernel logs..). There is a newer driver available at
http://218.210.127.131/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true
which is version 0019, as opposed to version 0017 currently in Ubuntu. I gave this one a try in maverick in an attempt to fix connection stability issues, but it did not seem any better than the version in Ubuntu (which I think was 0015 in maverick). But perhaps it fixes the kernel panics, so I will give it another try.

More interestingly, in the downloads page above there are drivers for other cards which use a new architecture, which allegedly fixes problems with the earlier versions. The architecture seems to unify the drivers for different cards. You can get for example the rtl8188ce driver, which supposedly supports 8192se too. I tried compiling this one under natty, but it hangs my computer. However at some point in the near future the new driver might be made to work correctly with the 8192se, so there's hope...
