In particular, David has access to the serial console on the machine. I was unable to decide with some certainity what happens, in particular, whether the machine was locked, only X was locked, or just keyboard and mouse input not working. But, the reliable state of the system where it spent quite a time during X startup was mtrr setup. Xorg was sitting in kernel, in i686_mrstore(). It seems that after some time, X starts sleeping in select(2). --s+08+7ZBU1+8TAHN Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkqyf7oACgkQC3+MBN1Mb4i7FQCgmVkSbV8NV657NrgWuCvnLXGs vRYAmwfG+nf7hY6unxzeqHXcv8w1IVv/ =4djk -----END PGP SIGNATURE----- --s+08+7ZBU1+8TAHN--
