This is a stretch, but one thing that comes to mind is a failing disk.
Often if a disk encounters problems reading and writing it will work
much harder. I'm not a kernel developer but there are areas of device
drivers that cannot be interrupted and this could be a problem.

Check dmesg and run smartctl to see if your disk is experiencing
problems.
