Hi,

Hm, isn't this also an issue in 2.6.25 as well? I've had a few very
strange reports of USB just locking up in 2.6.25, could this also be the
cause there?

As I wrote in the first mail of this thread the problem was uncovered on my machine by the following commit from 2.6.24-development:

commit e9df41c5c5899259541dc928872cad4d07b82076
USB: make HCDs responsible for managing endpoint queues

The interrupt problem exists also in 2.6.23 (and previous) but the USB code was not affected, as the old versions of the functions were using spin_lock_irqsave().

I just applied my patch to 2.6.24 & 2.6.25: it applies fine and compiles without problem. So it could be submitted to the 2.6.24.X and 2.6.25.X branches too.

Regards,

Stefan
