Can you please try version 2.6.42?
Sorry, typo. Actually, I am using version 2.6.42
Are you using pcmciautils or pcmcia-cs? Are you using an init script, or just plugging it in? What do you have in dmesg before unplugging it? I have the following in dmesg and your error suggests, that you have problems with IRQ. I do not know, but maybe it can help to use some irq-options on the kernel cmdline.

Answer is as expected (for non-German natives, it reads: "Go away!"): Ticket-ID CID771246 Sehr geehrter Herr Dahlen, wie Sie bereits befürchtet haben, können wir dazu keinen Support leisten. Da mir keine vergleichbaren Fälle mit entsprechneden SuSE Versionen bekannt sind muss es einen Zusammenhang zum verwendeten Kernel oder irgendeiner mit dem PCMCIA Bus verbundenen Komponente geben. Mit freundlichen Grüßen Dirk Hartel (AVM Support)
well, I do not think there is much we can do here :(
