The dmesg of the working kernel: http://grsecurity.net/~spender/dmesg.txt The output of lspci -vvxxxx: http://grsecurity.net/~spender/lspci1.txt The output of lspci -tvnn: http://grsecurity.net/~spender/lspci2.txt I don't have a serial console hooked up to the machine, and I'm not able=20 to scroll up/down after the panic, so I only have the following picture=20 =66rom the crash. I modified the code that spews out registers on a panic= =20 so that the context of the panic could be seen. The stack trace didn't=20 show anything useful, only repeats of an address similar to IP (for=20 which no symbols exist). http://img132.yfrog.com/i/img1457u.jpg/ -Brad --rwEMma7ioTxnRzrJ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFK0zWLmHm2SUJF1GoRAhKZAJ9MkeYGVOUbgQv+aXeYxSJM2dF5/ACdFYec YBBCnarE0iOlb98vFXrPUao= =TfXW -----END PGP SIGNATURE----- --rwEMma7ioTxnRzrJ--
