Wow, this is horrible. This patch should help a bit. But it's probably hard to workaround that DMA issue completely. There still is a chance of corruption, as soon as the kernel allocates and uses some memory that the DMA controller still uses from boot-up before the fixup is applied. --=20 Michael --Sig_/mkdRJKaGSTy4HU1PedsCf12 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJW/gAeAAoJEPUyvh2QjYsODT4P/0UYnvp08cylQ8zT3gStd9ZN CTWInlGKz5YFA5/2On1FX7u2yGdlZ6VtYISm7JP9CTWN+q5X78Fxg+jK3tjEzkJL O9RJEiyKqJrbnj4NK7vEXDm2Qz0ogfuiFOOId4qWFTXgRs/exlAMxeRpQgNTwvZO mh9JekQ3blBVV2f7oPkuDOAFZD20cZ3pLbFDr+UzciRmewI3RUqlQ0IoEn8Np+To wG16xhUGtH3Yza35Mb3kRhJVKTDP6kOfNmQHX7qt5NJsmKiTFtLRh2xalxtGmbC3 QzSBcHA1gJDwvXT7CYbm7TcSGD/O0vG5CsUNiAJg5hLiKRjS4FsoTSHKeD6Qo5pQ s/7dRxMGRrxN7gwqeyBxU7nZICp4CeRQkeL4TW6DL4/qgOr3n7zs2GQexw0sdmcD erJq9mCBbSPlFZdvGqnmMe1v9dZtIp2UJ4xuuoNQsJxjf3AEU4d8gHeOsnQXjYYD aRdqUWzaK5mVXfaDCgtS9/JIAqpu1iIm5f5heALTjoA05pv+j5XAyx90LgG6UlBY YC6PlOk4fjZ7TKQl26pHhnTrwldYOBuVC1mQOoBdq3EFzD7gUj73CMONx7qBYtYl g8jJmmOpvUW7/ahTL1caQ5J3HyTM2yP5J5C/sU4e2SSF1/4H2UHiTnkY9A7n+BmQ YWdpT4zR5E/cnjyxQ6/3 =VZwy -----END PGP SIGNATURE----- --Sig_/mkdRJKaGSTy4HU1PedsCf12--
