To allow easier debugging, I have now put our whole kernel tree up in a public (read-only) git repository at https://www.gibraltar.at/git/linux-2.6-gibraltar.git. The branch for this kernel is origin/gibraltar-3.0, although the above dump was produced by a version slightly "older" then HEAD, which did not yet have the latest PaX patch applied (no PaX and no lzma-squashfs in this kernel). Any hints/pointers/patches/etc. would be highly appreciated. best regards, Rene -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkp20DYACgkQq7SPDcPCS96R3QCdGTJsPiJGLfiWUZk67f6wms9Y rVgAoPMO2hnT3jwRtY0Qz40NRp0DpKxT =8NsP -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
