Yes, I did -- Greg merged the fix yesterday. However that bug would show up only in situations where the controller was removed (e.g., ejecting a cardbus card containing a UHCI controller). It's worth pointing out that 2.6.26 is a pretty old kernel. In the Bugzilla entry that roma1390 referred to (#13316), comment #3 reports that the problem was fixed back in May, 2009. (The other "me too" comments talk about different bugs, involving audio drivers rather than dvb drivers. At least one of them is caused by a driver trying to reload firmware at a time when userspace is frozen.) roma1390 should try using 2.6.34.
