Maybe memory fragmentation? Perhaps the driver tries to allocate a large block of memory and cannot find a continuous block of the right size. Maybe the driver developers used different kernel .config options than you are using. =20 Try increasing the value in /proc/sys/vm/min_free_kbytes. Try switching some things like SLAB or SLUB, try booting with kernelcore=3D512M to enable the Movable memory zone, or try 64-bit vs 32-bit kernels.=20 --=20 Zan Lynx --=-EoiYypk6TXvLZqh5JTYk Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.7 (GNU/Linux) iD8DBQBHxH7MG8fHaOLTWwgRAlMnAJ9ib1TYBP/raSIIQp2WIz1jSaIBuwCfZIGZ An3ApUucleETaoCZSBzarWM= =G2fr -----END PGP SIGNATURE----- --=-EoiYypk6TXvLZqh5JTYk--
