Hi
I've met an issue with FreeBSD 11.1 Release and VirtualBox 5.2.6/5.2.8: Windows guests are freezing time-to-time. Under heavy load guest might fall into BSOD.
I've googled and read lot - tried different settings - no luck
Then I found an old bug: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=168298
And compared VBox guests logs from two different hosts: FreeBSD 10.3 and 11.1. Found the following:
On 11.1:
while on 10.3 I see:
As I know - AIO is built into kernel starting from 11.0.
Is there any way to turn it off?
Thank you.
