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’m 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’s going on and he has provided us with a lead. We go from there... -- Marcel Moolenaar marcel@xcllnt.net [-- Attachment #2 --] -----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-----
