Failures may not always be obvious. The ia64 kernel has a fixed array for relocations and a harmless piece of code, which may actually never be called, could result in additional relocations that case the array to overflow and do bad things on boot. All I=E2=80=99m saying is: give Anton the benefit of the doubt. He has = spent a lot of time with ia64 and knows quite a bit about its behavior. We simply do not know what=E2=80=99s going on and he has provided us with a = lead. We go from there... -- Marcel Moolenaar marcel@xcllnt.net --Apple-Mail=_F860F49E-8F88-4A5C-91E6-E7F7EF6961DC Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQIcBAEBCgAGBQJV31kgAAoJEIda8t8f0tjjVDYQAOCWN9eh92siyrF4zUar+VIO sIeCmt8xqWw6Lnwn9JRpxWjAOpbQ72ISo3jClEtjsZVU9QnlMPx+3ohnkvbqYEXP 3UFfHPGz7/WQbrbnkyAuu/ZNchXEX+Kmog9AeK5GdMn85MY5fM7G/KnAJ89biyPX hjOywrvNJ10IQzK5Jw+RdrWxMip4Q2DsW5ZW6dmOXJP9vJnsWtuUgvARPyCbA52q Af06zadH0qcUlQyMk/B1NJF1A75rUQo/tUyraCIXhGHdUPuqknxYsPq975AfzFyz 3vOPbDyJHxGplIhnrNXKKB36bR1D2D3qVEIP5jvhWGL8Lb8/knKZHCOw79a+E/dO UM1ILsp2/8cSAORvtHuzZV4PBYmj/BrqXybBrmGcrxkjM9s5S7eeRUxM9S3GX8qx R1dsrTuD7o4CYRD1bQBsNdIStcoCQojIs42AxOq4HREF5GNqQBRgfKZKEPrijP0C wQe3aqD1ZYSOMoPqh57GP6pgEKg9F//v8d5DfaxkwQ5y8dvj0iCg+4Pici1rF1rT WKFDu3ohe3sUH7rXv82Lq5i+qPgDz+fYvBNrfD5H82YIM/V4dJbtrC8BWhglf7ta il8zhNHFFphI/oDNmuqm0ZBS439c04eB3ZGMCueZWPhlL/Xk50XVv3dew+DW5lHt qTnCv2354wdbBFcKzXx1 =Ef5d -----END PGP SIGNATURE----- --Apple-Mail=_F860F49E-8F88-4A5C-91E6-E7F7EF6961DC--
