Subject: Re: [PATCH v3 00/77] More fixes, cleanup and modernization for
 NCR5380 drivers

Hi Finn,

I've tested this series thoroughly on my Atari Falcon - no regressions,
runs stable and is quite responsive. No SCSI lock-ups that had plagued
the old driver (before your rewrites).

Please add my

Tested-by: Michael Schmitz <schmitzmic@...il.com>

Cheers,
