New ZFSv28 patchset for 8-STABLE: ARRRGG HELP !!

[Jean-Yves Avenard]

Well

Today I added the log device:
zpool add pool log /dev/ada1s1 (8GB slice on a SSD Intel X25 disk)..

then added the cache (32GB)
zpool add pool cache /dev/ada1s2

So far so good.
zpool status -> all good.

Reboot : it hangs

booted in single user mode, zpool status:
ZFS filesystem version 5
ZFS storage pool version 28

and that's it no more.. Just like before when I thought that removing
the log disk had failed.

This time no error nothing... just a nasty hang and unusable system again...

:(
