Add printks. It happens with both, and that's why I think this is not a problem with the rt2500 driver(s), but somewhere else in the kernel. But I do not know where, because it is a lot bigger than the rt code base. >Try to reproduce the problem from the console, you're more likely to get >a usable Oops. > I did, it just locks. No reaction to Sysrq+T/+P, which is the "hard" in "hard lockup".
