This is even more serious than the one in 10.04. While in 10.04 the bug would slow down the machine for a while in 10.10 with 2.6.35 kernel will simply hang the machine and requires a reboot (which can only be achieved by rebooting from the AWS console multiple times) of the instance to be "fixed".

I'm in the process of upgrading all of our instances to Natty from 10.04 or younger. It's actually weird that this issue didn't get any attention whatsoever.
