I have the same problem since ubuntu 7.04 and also on jaunty 64 bit
version.
My hardware is an acer aspire e360 with an athlon 64 x2.
the final lines of my dmesg are:
[ 6672.296067] usb 2-6: new full speed USB device using ohci_hcd and address 5
[ 6672.506947] usb 2-6: configuration #1 chosen fr
I have also this problem expecially at the end of the animation/film.
I have an AMD Athlon64 X2.
If i restart the Firefox browser the plugin restart normally.
On same sites the problem wasn't verify.
