mav 2011-04-19 16:43:55 UTC FreeBSD src repository Modified files: (Branch: RELENG_8) sys/dev/ahci ahci.c Log: SVN rev 220850 on 2011-04-19 16:43:55Z by mav MFC r218596, r218605: Disable NCQ for multiport Marvell 88SX61XX SATA controllers. Simultaneous active I/O to several disks (copying large file on ZFS) causes timeout after just a few seconds of run. Single port 88SX6111 seems like not affected. Skip reading transferred bytes count for these controllers. It works for 88SX6111, but 88SX6145 always returns zero there. Haven't tested others, but better to be safe. Revision Changes Path 1.1.2.47 +13 -6 src/sys/dev/ahci/ahci.c
