So it could be related to PCI-e / PCI bus bridge; maybe some hotplug or power management event interrupt. The five minute delay could be a hint that it is related to power management. Are there perhaps BIOS setup options to enabled / disable power management for PCI-e devices? -- This message posted from opensolaris.org
