https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=168298 rkoberman@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rkoberman@gmail.com --- Comment #5 from rkoberman@gmail.com --- Just for the record, this is not ZFS related. The same issue shows up with VB and UFS. I am running 11 where AIO is integrated into the kernel, so I'll try the tuning advice and see what happens. In my case it produced several crashes in my Window 7 client while suspending the VM and many hangs of the VM. Worst case was when the virtual disk required a disk check which, in turn hung repeatedly, though eventually it did complete and the system is running again. Can AIO be disabled? I was looking at kern.features.aio. virtualbox-ose-5.0.26_1 FreeBSD rogue 11.0-BETA4 FreeBSD 11.0-BETA4 #1 r303806: Sat Aug 6 18:50:50 PDT 2016 root@rogue:/usr/obj/usr/src/sys/GENERIC.4BSD amd64 -- You are receiving this mail because: You are the assignee for the bug.
