I am on 11.4-RELEASE-p3, ports tree updated today. I compiled emulators/virtualbox-ose-nox11 from source and fired up a virtual machine. = As soon as it tries to write something to disk, with 100% repeatability, the VM freezes. Here the relevant output in dmesg: pid 3091 (VBoxHeadless) is attempting to use unsafe AIO requests - not logg= ing anymore The VM has a single, zvol-backed disk. -mc. --=20 You are receiving this mail because: You are the assignee for the bug.=
