Hi,
I have an unusual problem. Last night I tried updating from my
old-ish kernel/world to an up to date version. I had been using
202500-ish successfully. I can build and install the newer world and
kernel fine, but when I reboot I get the following
Trying to mount root from zfs:raid250/root
ZFS WARNING: Unable to open /dev/ada1p3 for writing (error=1). ZFS
WARNING: Unable to open /dev/ada2p3 for writing (error=1). ROOT
MOUNT ERROR.
If you have invalid mount options, reboot, and first try the
following from the loader prompt:
set vfs.root.mountfrom.options=rw
and then remove the invalid options from /etc/fstab
loader variables:
vfs.root.mountfrom=zfs:raid250/root
vfs.root.mountfrom.options=rw
Im using 2 drives in a ZFS mirror configuration (ada1 and ada2
making raid250)
I tried going back over the older revisions, and the last kernel
that I can build and boot is 203503. It seems the changes in 203504
are what cause me the problems.
Now for the weird bit, I took a friends kernel (204324) and that
boots fine. I pulled his kernel configuration and built against that
(I had decided to remake my kernel configuration just before I tried
updating). Still I get the same error. I have checked my
/etc/make.conf and that looks right.
I attached my /etc/fstab and /etc/make.conf. Im using an Intel
Q8300 running amd64.
Anyone have any ideas? This is my work computer, so unfortunately I
wont have access to it over the weekend but will be able to give
more information if required on monday
Cheers
Paul

Are you sure you are allowed to use these flags to compile the kernel?
I would try removing this line completely.
CXXFLAGS+= -fconserve-space
#CFLAGS= -march=native -O2 -fno-strict-aliasing -pipe -s
#CXXFLAGS+= -fconserve-space -fpermissive -Wl,-rpath-link,/usr/local/lib/gcc44

These options dont appear to be passed in when building a kernel. In
fact -mno-sse3 and -mno-mmx are passed in to make sure that these
options dont not get feed through. Here is a piece from a kernel build
with these options still in my make.conf
cc -c -O2 -frename-registers -pipe -fno-strict-aliasing -march=nocona
-std=c99 -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes
-Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef
-Wno-pointer-sign -fformat-extensions -nostdinc -I. -I/usr/src/sys
-I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS
-include opt_global.h -fno-common -finline-limit=8000 --param
inline-unit-growth=100 --param large-function-growth=1000
-fno-omit-frame-pointer -mcmodel=kernel -mno-red-zone -mfpmath=387
-mno-sse -mno-sse2 -mno-sse3 -mno-mmx -mno-3dnow -msoft-float
-fno-asynchronous-unwind-tables -ffreestanding -fstack-protector
-Werror /usr/src/sys/dev/pccbb/pccbb_isa.c
However, the world will include these options is there are in the make.conf
