I think that is fixed upstream as https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=46ca3f735f345c9d87383dd3a09fa5d43870770e Created attachment 282721 [details]
Additional locking for vt code
When I initially reported this problem in 2017, I received an almost immediate response from Brad Spengler. He said that there is a race condition in the vt code causing this problem and provided the patch attached. That patch reliably fixed the problem for me, and it still applies (I'm still using it for 5.0, without any observable negative consequences). I asked Brad Spengler to send his patch to the kernel maintainers, but he didn't. |
