Essentially, this says that your SATA controller hung in a bad state
that isn't recoverable:
https://github.com/illumos/illumos-gate/blob/master/usr/src/uts/common/fs/zfs/spa_misc.c#L256-L261

I'd suspect the SATA controller. If this panic comes with any
regularity, try working around the SATA controller by using a substitute
HBA and disabling the old one to see if it goes away.
