Device not defined or unavailable Both systems use the stock GENERIC kernel, i.e. -9 had full diagnostics bui= lt=20 in (and was run under VirtualBox) and -8 had no diagnostics (and was run=20 native). =20 A LOR is produces prior to freezing under -9 (quiet a time prior). See=20 kern/141950. =20 The script uses unionfs to build ports (in an attempt to create a tinderbox= =20 without the need to delete and/or extract packages). To use the script to: # mkdir /tmp/localbase /tmp/builddir # env LOCALBASE=3D/tmp/localbase BUILDDIR=3D/tmp/builddir ./ports-union-bui= lder.sh This will try build everything for x11/xorg. =20 Is it possible that VirtualBox is interfering in getting usable diagnostics= =20 for -9 and how can I setup a dump device for -8. Currently I have: # swapinfo Device 1K-blocks Used Avail Capacity /dev/ad4s1b 8388608 0 8388608 0% /dev/ad8s1b 8388608 0 8388608 0% Total 16777216 0 16777216 0% Any advice?
