I dare to doubt there are two severe bugs of that kind that are 100% reproducible. I haven't had a hotplug crash in any of the two drivers for a long time, and I use both of them extensively. I rather assume there's something else failing, probably some host controller issue that corrupts mempory? Can anyone else reproduce this maybe?
