Turns out it wasnt fine in CIFS. I figured out the problem has to do with PCI cards. The nics work fine as long as the SATA controller add-in card is not present. The SATA controller works fine as long as I don't send data to or from the add-in NICS.
I even removed the nics and replaced them with one PCI-E card for testing (also an intel nic) because in the MoBo drawing it shows that the PCI-E slots have a direct path to the chipset. All the devices seem to work just fine in windows 2k3, which is frustrating. Is there anything to be done to make OpenSolaris communicate to the hardware more reliably? Are you still having the same issue? -- This message posted from opensolaris.org
