I got the following oops on startup while mounting the root filesystem. Unfortunately there was no "Code" because of a bad EIP value. If anyone would like more information or anything for me to test, please CC me.
I would like to remind some people that preX kernels aren't exactly considered stable - _these_ are the kernel's Linus releases for public _testing_. While a large change to the VM is pretty drastic, its pretty clear that Linus is under a lot of pressure to "fix" it. Maybe if we can think of a way to improve the vm without changing any code or add a /proc/sys/vm/bugs interface, we should!
Cheers, Nick
