Hello, Freebsd-stable.
I have VirtualBox-based FreeBSD 8.1 installation (32 bit, VirtualBox
3.2.8, WinXP/x64 host, but I thinks that host config is irrelevant).
Two virtual HDDs are atteched to virtual SATA adapter (channels
0 & 1) and CD/DVD attached to virtual IDE adapter (Primary master).
I've used FreeBSD 8.1-STABLE builded about two months ago and
everything worked Ok with "Standard" (not AHCI) driver, root FS is
ad4s1a.
I've updated FreeBSD today (12/09/2010) with csup &
buildworld/buildkernel/installworld/installkernel (GENERIC kernel).
Nothing was changed in VM config/setup.
Now it can not be booted because KERNEL doesn't see any HDDs and
can not mount root FS. It shows only "acd0" as "GEOM managed disk device".
bootloader sees disk and reads kernel & modules without problems.
I've tried to "load ahci" on boot prompt, but result is almost the
same. AHCI driver sees two channels, but got timeouts on both --
oops, can not mout root FS again.
I've tried to load "vboxdrv" (it is build right after kernel &
world, so it should be in-sync), but here is abother fault: kernel
panics in "(swapper)" process right after "acd0" detection (wihtout
vboxdrv kernel complains about missing root FS exactly at same
moment).
I've googled this problem, but without any success. What should I do
to revive my VM?
