Is it posible to run FreeBSD/sparc64 on SunFire V215?

Well, I don't know how frequently you've hit this problem
before (was it always in the 1-2 days range?) but an uptime
of 8 days without seeing an unsolicited interrupt ACK/NACK
indeed suggest that the bug fixed was the culprit in this
case. I haven't seen this issue myself as I had fixed the
bug here before upgrading my v215 to SMP. FYI, pending
some final tests I think that the code for supporting
PCIe-based sun4u machines is now ready for hitting HEAD
(but given that it touches several pieces, commit it while
take a bit).
