Hmm- the platform code that allows an HBA to map buffers for a
transfer is returning EAGAIN- that's more of a generic platform
problem. Did it used to work okay and just broke recently?

The pkc0 is the ISP chipset. It's possible that the firmware being
loaded into this by the isp driver is fouling up what the SRM driver
thinks should be going on. You can check this by building a kernel
with

options ISP_DISABLE_FW

added to it. Try that and report back?
