I cannot answer your question, at least not without some additional data. Still, does it work if you revert the r265843 ? Do you have INVARIANTS defined in your kernel config ? Do you have vmcore from the panic ? If yes, please load it in kgdb and do p *(struct vm_page *)0xfffff800fc480870. The noted revision should not affected the sparc64 pmap and tsb, but still please try to revert it and see. --p+IlF8Xh9KY56wTg Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (FreeBSD) iQIcBAEBAgAGBQJTbqCfAAoJEJDCuSvBvK1B+3wP/3SR7eskFCLgwUgHZct+5SSE dV4sJbfGZI5CwkXEKw7HcHrOAY+W9FASVLl++qwzBzuNnPqrhSOkdKxhR0lhqcGP 1g4JPZ9DGQ3XDemUjV3C8xzu//G1E0p6bh+Pahq/sqT3pOESlsxk1cow/tBMgvEE OIXZkSlJQjp7lPcvOehJB2N7EtQrJO89Zn3bzkbTWSceOkd1+4UXhyfNsKsxuB2U jh/ilZUZeK/Z8EZILgDP6Cs3xgNLYOP17qPrqqaLF1zkUSII0R7W4mVjEqawdShg ebl+CO2QJXFvPmuC0y/C4sCK/z+eS9kaGBhq2O4z2FA8WMahQc70Rq531rIUFTbg 6PLcG6Ezk0oJgIK6smtD0DCBId+LPNsjFuOknrrMiwByQnVy0EM2Jwgo753nx5aH ciXT7+rlWriO4uWOthkrYobWeXODkFkeNBnU7w/r2m7iVU0kGl5eyVol0V4ldV5W CcqdKrn3FPax85P50cTYLAZDfjBV4M7VvPLfrkkoBcFdIUko94ylKinYlc0hfDlZ J4qOrpm99uADIbKlO6+ViCjNTQjr1fWthF1u+fwgoCdFYcFvj0feHSPw9Q4TtJtb i0X840J5mpAnhuHboEwHEc8aNSD9J0oRafLOoCzOaDNYcwVXriBWAhXAn+3LK4Kg tLomUPOjyQ+5AIwJoYaK =sNmh -----END PGP SIGNATURE----- --p+IlF8Xh9KY56wTg--
