I've been having some issues with a server crashing randomly. It seems that the AHCI watchdog is marking both disks/buses down simultaneously, and understandably solaris freaks out without any disks attached. The system completely locks and requires a hardware reboot. Upon reboot, everything is fine, zpool status reports both disks online, cfgadm looks fine.
/var/adm/messages shows: Jun 14 03:16:36 tank ahci: [ID 372819 kern.info] NOTICE: ahci watchdog: port 0 satapkt 0xffffff02dee429a8 timed out Jun 14 03:16:36 tank ahci: [ID 372819 kern.info] NOTICE: ahci watchdog: port 1 satapkt 0xffffff02ddca9c40 timed out Any idea's what could cause both disks or sata ports to timeout simultaneously? Im not having any issues at all with the other 4 disks connected to the same ICH9 sata controller, only port 0 and 1 (which happen to be root disks). All hardware is new. Motherboard is a Gigabyte EP35-DS3P (6x ICH9 ports, 2x Jmicron ports), 2x WD5000AAKS root disks (mirrored zfs), 4x WD10EACS storage disks.
