Emn, how recent are those signal-handling changes? Remember, the kernel on the gadget is only 2.6.20.1. And macroscopically it is indeed 100% repropducible - with and without sync. Can it really be explained by this signal-handling problem? > It hasn't been accepted yet, unfortunately. If you can confirm that it > fixes your problem, I'll urge Greg to merge it in time for 2.6.22. I'll try to test it tomorrow.
