Did you already ask PC Engines? They might recognize the problem. Either 5536 or the driver may still be the problem, but I think it would be interesting to ping the vendor.
Sure, sounds wise enough... I just sent an email to their support address. But searching their forums, I saw some advice to disable ehci altogether in case of issues. But that makes it works at USB 1.1 full-speed, which I would prefer to avoid for obvious reasons.
If you'd rather collect more data first then you could compare with a different operating system running on the same hardware.
This is going to prove difficult, as the board is used as a quasi-production system. I can tinker with kernel compiling options/patches but I definitely have no possibility to put together all that is running on it with another OS.
In fact, I was hoping that someone could enlighten me on the meaning of the succession of kernel messages.
In the meantime I will disable USB power management and confirm my first guess on the issue being PM-related.
