It's even worse - or my memory is, actually.

With dock, both 2.6.32 and 2.6.31 exhibit the problem, so it's not a 
recent regression - but the bugzilla entry still holds.

In fact, googling tells that I reported the issue back in 2006 together 
with a USB problem that I thought was related, and that has been fixed 
meanwhile:

Strange that I haven't noticed it meanwhile.
