Sorry for the late response here, but what you're describing matches fairly well what I saw with RELENG_8 (just after 8.0 was released), but luckily I didn't have any disks on my MPT, just my tape autoloader. Random timeouts, and then bus resets (that made tape IO unreliable). The bad news, is that I had the exact same trouble with OpenSolaris (134), and something-similar with Linux (can't remember versions), at the time. I never did find a solution, and ended up throwing windows on the box, just to get reliable backups. My MPT is a 3801 LSI1068e based card running the latest bios. //Svein --=20 --------+-------------------+------------------------------- /"\ |Svein Skogen | svein@d80.iso100.no \ / |Solberg =D8stli 9 | PGP Key: 0xE5E76831 X |2020 Skedsmokorset | svein@jernhuset.no / \ |Norway | PGP Key: 0xCE96CE13 | | svein@stillbilde.net ascii | | PGP Key: 0x58CD33B6 ribbon |System Admin | svein-listmail@stillbilde.net Campaign|stillbilde.net | PGP Key: 0x22D494A4 +-------------------+------------------------------- |msn messenger: | Mobile Phone: +47 907 03 575 |svein@jernhuset.no | RIPE handle: SS16503-RIPE --------+-------------------+------------------------------- If you really are in a hurry, mail me at svein-mobile@stillbilde.net This mailbox goes directly to my cellphone and is checked even when I'm not in front of my computer. ------------------------------------------------------------ Picture Gallery: https://gallery.stillbilde.net/v/svein/ ------------------------------------------------------------ --------------enig1C9D8BE22A5CD5A921D0B1B7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxFk48ACgkQODUnwSLUlKSExQCeONKY0PZSJCL+6RKURaZax2JU NeIAoIaFZN91ghfF1QF97Gozbo8kyZaZ =R8hO -----END PGP SIGNATURE----- --------------enig1C9D8BE22A5CD5A921D0B1B7--
