A workaround for the hang on boot and "error 1 lba X" failures is the
following patch, it would be interesting if it also makes the
zfs_alloc/free error go away too.
After applying the patch zfsboot and gptzfsboot boot successfully.
Tested both inside qemu and only gptzfsboot on a living system.
Hi,
Can you please try the following alternative patch, which should fix the
problem without disabling -mrtd? E.g. revert the previous patch, then
apply this one.
Of course, if any other posters in this thread that had problems with
gptzfsboot (or 'plain' zfsboot) can also confirm this patch works, it
would be nice. :)
