@johalun : What version of code is this? Is this the code with the added state-bits needed for 4.15?

johalun commented 6 years ago

Yes, with 4.15 branch in freebsd-base-graphics

It might be super simple to fix. We need to handle task-killable case I think.

Assert panic is fixed although the case of TASK_KILLABLE might require additional handling in linux_schedule.c.
