Hello, My libmap.conf contains currently:=20 libpthread.so.1 libc_r.so.5 libpthread.so libc_r.so which is how I understood the UPDATING entry. Without these entries or when mapping libc_r to libpthread, OpenGL applications will core dump. I understand that mentioning "libGLcore + NVidia" makes one think about the pthread issues, but I don't think that this is the case here.=20 I did the linking of the same application again a few minutes ago, and it worked. The messages I do remember did say something that the libGLcore.so was invalid. I did not reinstall the nvidia drivers after the crash because everything worked, so I really cannot see what could have happened.=20 Perhaps some stupid bit flipped at the wrong place and time, and triggered everything else (linking triggered hard disk activity, hard disk activity and xawtv triggered panic, panic happened at bad moment so the bremfree thing happened. That is currently my "explanation" :/) Regards, Andreas --=-PfEUKUeralLNo/+pCz8o Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQBAM7M3Yucd7Ow1ygwRAlQ/AJ9DXtIcpbJSaKocYYKKKc/o43PATQCdHPvH iHwwyZ6eYW0/A7VCgLHPrT4= =40Tm -----END PGP SIGNATURE----- --=-PfEUKUeralLNo/+pCz8o--
