Last week-end (25/26 august), I dist-upgraded my ZFS root install...
unfortunately, I haven't been able to boot it since :-(
I got an upgraded kernel (4.17.0-3), but even trying the previous
know-to-work 4.17.0-1 doesn't work. The kernel loads,
but nothing happens once the ZFS module is loaded:

ZFS is on sdd2.

The initrd were rebuilt at the time of upgrade, dunno if it matters. I
have tried
upgrading since then (I still can mount the ZFS root from a previous,
non-upgraded, non-ZFS install on sdc),
but it doesn't help.

Any suggestion or idea welcome...

BTW, did anyone else succeeded in having ZFS root on sparc64?

Cordially,
