Bug Description
Reloading the Hyper-V LIS modules can sometime result in a kernel panic.
Technical details: a hypercall can return “invalid alignment” error if the input parameter spans a page boundary. Updated LIS code handles properly the error without returning bug().
We've triaged this issue internally and the following 2 patches have been created.
Please include them in 14.10 (Utopic Unicorn) daily builds and let us know when we can test.
