Comment # 20 on bug 1083866 from Steffen Ungruh

So, to sum up what we've learned so far:

1.  All kernels are affected.

2.  The distro kernels break within a very short timeframe after reboot.

3.  The vanilla and bisected ones are totally erratic. Sometimes they break,
sometimes they don't. (In my last case within a second after network use)

4.  And, arch-kernels are also affected.


My questions:

What differentiates the default and vanilla kernels when it comes to USB power
management?

How can I test this more efficiently? Meaning, how can this error be provoked.
Waiting for something to happen/not happen has proven completely unreliable.
