Building debug versions is most easily done via `make DEBUG_FLAGS=-g` in path/to/src/boot when building natively. You can also add the same when cross- compiling but then you'll end up with debug versions of everything. In both cases, make sure to not have any old object files in place. > > Also I tried zfsloader builded from sources @ may 2012: > (same zfsboot, but used zfsloader.old) > Boot device: disk File and args: > > >> FreeBSD/sparc64 ZFS boot block > Boot path: /pci@1c,600000/scsi@2/disk@0,0:a > Consoles: Open Firmware console > ofwd_open: Could not open disk1: > ofwd_open: Could not open disk2: > ofwd_open: Could not open disk3: > > FreeBSD/sparc64 ZFS enabled bootstrap loader, Revision 1.0 > (root@sunspot, Fri Nov 2 08:59:22 MSK 2012) > bootpath="/pci@1c,600000/scsi@2/disk@0,0:a" > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > ZFS: i/o error - all block copies unavailable > can't load 'kernel' > > What's wrong? No idea; looks like either an older ZFS loader can't deal with current ZFS or something is fundamentally wrong with your ZFS setup. I don't know enough about ZFS for telling what's the problem here. You're probably off asking ZFS people about this. > Could it a result of crosscompiling?

But yes, I also see this and also in other occasions and on other architectures as well. Marius
