Is some general method for solving this issue?
Sorry for the late reply -- I wanted to attempt to recreate the issue. Unfortunately(?) I am not seeing any such problem. My card is a PCCard apparently sold by CompUSA, but the chipset reported in dmesg matches yours (i.e. RTL8185vD + rtl8225).
I have tried vanilla 2.6.34 and 2.6.35 as well as the Fedora-provided 2.6.35.6-48.fc14 -- all seem to work equally well, despite the annoying warning that continues to pop-up during scans. (I need to get that fixed in Fedora!)
Could you try using netconsole to capture a backtrace over an ethernet connection?
If that doesn't work, you might try doing a git bisect from the last working kernel (2.6.33?) to the first broken one (2.6.34?).
Thanks,
