Hi!

I have an rtl8187, the variant that shows:

Bus 007 Device 003: ID 0bda:8197 Realtek Semiconductor Corp. RTL8187B
Wireless Adapter

with lsusb. I use Ubuntu Intrepid, kernel

Linux satellite 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009
i686 GNU/Linux

the latest drivers from

compat-wireless-2009-02-25

installed, working (the driver that comes with the kernel doesn't
suspend, ever). It works quite well(yes, I also have signal issues,
etc.), but I just suspended a moment ago, and I got a nice kernel panic.
I am sure this is due to the rtl8187, as it is meant to be experimental
(since it's a B variant). As a side-note, this is not the first time I
got a panic due to this driver, and all the time the panic's message
either contained something to do with 80211 or with the rtl8187. The
panic's screenshot is attached.

I hope this info helps someone get this driver more stable :)

Bests,

Mate

PS: The computer is a Toshiba Satellite laptop, with integrated rtl8187

It is  known issue - there are some work-arounds, and work-in-progress patches:
