illumos kernel finally (after more that a year) is compiled from sources.
Sources are at state of October 2012 with these fixes:

• 3443 Missing curly-braces in one ixgbe file.
• 995 boot message: No randomness provider enabled for /dev/random

Note that old zfsutils will not work on new kernel,
and new zfsutils will not work on old kernel.

Known issues:

• There are warnings about multiple defined symbols in kmdbmod
• Closed source drivers are missed (more warnings from scsi drivers)

Discuss at dyson-devel@osdyson.org or #osdyson at irc.freenode.net.

How to jump onto new kernel:

1. Create a shapshot of your VM !
2. Update APT repository:
   

   apt-get update
   

3. Make sure you have new bootadm:
   

   apt-get install bootadm
   

4. Create a new "BE":
   

   zfs snapshot dyson/root@new
   zfs clone dyson/root@new dyson/new
   

5. Mount devices under the new BE:
   

   mount -F lofs /devices /dyson/new/devices
   

6. Sweep out old kernel and its configs - FROM JUST CREATED BE!:
   

   chroot /dyson/new apt-get purge illumos-kernel
   rm -f /dyson/new/etc/devlink.tab
   rm -f /dyson/new/etc/minor_perm
   rm -f /dyson/new/etc/driver_aliases
   rm -f /dyson/new/etc/driver_classes
   rm -f /dyson/new/etc/name_to_major
   rm -f /dyson/new/etc/security/device_policy
   rm -f /dyson/new/etc/security/extra_privs
   rm -f /dyson/new/etc/path_to_inst
   

7. Install new packages into new "BE"
   

   chroot /dyson/new apt-get install illumos-kernel zfsutils
   

8. install 32-bit libraries for componentents which are still 32-bit:
   

   chroot /dyson/new apt-get install lib32zfs1
   

9. Create boot archive:
   

   bootadm update-archive -R /dyson/new
   

10. Add a new GRUB entry:
    

    vim /dyson/boot/grub/menu.lst
    

11. Add these lines (copy previous and edit bootfs and title):
    

    title New Kernel
    findroot (pool_dyson,0,a)
    bootfs dyson/new
    kernel$ /platform/i86pc/kernel/amd64/unix -B $ZFS-BOOTFS -m verbose -k
    module$ /platform/i86pc/amd64/boot_archive
    

12. Reboot and remember to choose New Kernel in GRUB menu:
    

    sync
    reboot
