I've confirmed that particular problem is bug 209821. I've disabled EFI and GENERIC r362848 boots and runs successfully. >> Does anyone have any ideas? > >Did you checked that the physical devices where your ZFS pool is located, >are detected, and that kernel messages for their drivers are as usual ? >Overall, is there anything strange in the verbose dmesg ? There's nothing obviously strange (in particular, I can see the physical boot/root disk) but the faulty kernel appears to have moved the msgbuf somewhere unexpected so it's not saved across reboots and I'm limited to eyeballing the messages via DDB. Since GENERIC worked, I did some more experimenting and tracked the problem down to a lack of "options ACPI_DMAR" in my kernel config. That makes more sense, though I have no idea why it suddenly became mandatory for my system. --=20 Peter Jeremy --/9DWx/yDrRhgMJTb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE2M6l8vfIeOACl4uUHZIUommfjLIFAl8WCqRfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEQ4 Q0VBNUYyRjdDODc4RTAwMjk3OEI5NDFEOTIxNEEyNjk5RjhDQjIACgkQHZIUommf jLLzuA//ccCK8h3qEGfVXs+JQPXtrL0FPq2GQ27iTFK3PhGUaBQoeJ08wBkhO8jE Z/7RYS14vwURWb24YGSCHk2RknHbay/WH/gpBwOU5aDD0zNG3r5JiSFcjy6/9sRL SYl5Dtt61FjxzAcLwUHUYv81aYND8g5oqznJVrvL9sf2h79/5IH23KY7y5WnhcXo ygGAwzNpPCBs8gk++BbhcJxX1XqLkbyk1Ty5NehYOXW8U8PtTSzKArhq3na2r1iD gwLJJznzWeaCOJHkVdy9l+cT+d4brSOWiMoHrmeSQofd/UT6MxCFDi+kLEHOSW22 Za2t18dBq8zltiBbcJXl+KgQ6KFrxZtEJSm1pruVkSSHXL+BdXjY9SxSvMbnJ0aD 1izpqCsf4huBcegTA9aOA00Z3wDfoSdExBxNiATq2qb98+EI7Lr0AIyN3FmjMjbj 8bIx4TFhJtw4Isctms/5APMZN+LpRFMMKm+7tYdxMVTFYQBgL10CYTeUQBpT3sre 3wj5CsT+s15sRBvxtezRpBtcc7ol0yGIUCELdrVJ1EBJc01NigYOA9t7sSfHixmd qgDzUg+JDuUFoSHJonIREVbNFWwxDANPsUTzmuYqbhL1VS0smCsYmKbuZgL/P/Bl UICxlcvpKmWhGj2ByrMaJB3WkU4Fm+TfwIVMzRC73Lvg3TYoweE= =pOkP -----END PGP SIGNATURE----- --/9DWx/yDrRhgMJTb--
