I would expect messages to be logged by the isp driver, or the CAM layer, or even GEOM, but there is nothing there - only this "fsync" message. =46rom the code, it looks like an transient condition (printed in the cas= e of EAGAIN), but the hardware here is behaving a bit suspect so I'd like to make sure - should I ignore this message? --------------enig1A8FB78AEA4D6626C31A47B7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9OB00ACgkQldnAQVacBcj7FgCfSUqoXYRAPBW2EhRKVTUUx2lg rJIAoKgpdh6B5xejCwIr6Lv3AoShvtht =Ucqp -----END PGP SIGNATURE----- --------------enig1A8FB78AEA4D6626C31A47B7--
