FreeBSD 8.2 amd64 SiI3132 SATA controller Seagate Barracuda LP 2 TB sata disk Disk has been working fine for ~1.5 years, zero problems. Suddenly: siisch1: DISCONNECT requested siisch1: siis_sata_connect() calling DELAY(100) [ previous line repeated a gazillion times ] siisch1: SATA connect timeout time=10000us status=00000000 siisch1: SIIS reset done: phy reset found no device (ada5:siisch1:0:0:0): lost device (ada5:siisch1:0:0:0): Synchronize cache failed (ada5:siisch1:0:0:0): removing device entry siisch1: CONNECT requested siisch1: SIIS reset... and the disk comes back. After umount/fsck/mount it is working ok again. Smartctl doesn't report any problems. System has ECC memory, conditioned power, air conditioning, ... I looked at siis.c but didn't find any clues. What would cause a disconnect request out of the blue?
