hardware of my ThinkPad T42, lspci -nnvv

While looking for stuff in the logs for bug #16376, I found the following backtrace in the log:

I believe they have been introduced with some recent kernels, as I do not remember having seen them before. At least 2.6.34 and 2.6.33 are affected:

But there have been lots of card removals without that backtrace.

Its a warning. Is it harmless?

This is happening on a ThinkPad T42. I will attach the hardware configuration with the PCMCIA card attached. As an excerpt here the Silicon Image eSATA controller from Delock:

Comment 1 Martin Steigerwald 2010-12-07 21:26:51 UTC 
Happened some other times. A race condition?

Comment 2 Martin Steigerwald 2013-01-12 17:23:58 UTC

I am closing this. Will reopen should I notice it again.
