Commit a4a23f6 basically just changed a kzalloc and memcpy to the single kmemdup call[0]:
- input_device->hid_desc = kzalloc(desc->bLength, GFP_ATOMIC); + input_device->hid_desc = kmemdup(desc, desc->bLength, GFP_ATOMIC); The Oops you see now still seems to be mm related: RIP: 0010:[<ffffffff813693c2>] [<ffffffff813693c2>] memcpy+0x12/0x110 This may indicate a bug deeper in the memory management subsystem. I'll take a look at the commit log between 3.10 and 3.11-rc1 to see what changes were made there. It may require us to bisect further with commit a4a23f6 reverted, and looking for when this new oops with memcpy started.
