Should we encourage folks to just configure their VMs to use xbd? I = hope some day that the system will just report "da" devices, so the ada = name may change again. We could also suggest specifying SCSI disks in = the VM config since I don't think "da" will ever change. > Additionally, I've applied the patches from FreeBSD-SA-13:06.mmap, = rebuilt the kernel and rebooted, and the system now works fine. >=20 > I did note however that rebuilding the kernel takes an awful lot more = time than on a FreeBSD9 system.

It would be interesting to know your = results building stable/9 sources in your 10 environment to see if this = is just due to "build bloat" or a true performance regression. -- Justin=
