As reported on -current, I used to have this problem, but it seems to have been fixed with the latest BIOS update (T61): Before the BIOS update, C3 caused similar lock ups in syscons when running on battery (it did work in X). When on AC, there has never been any problem. I made available some information (dmesg, kernel config, acpi dump, dev.cpu and hw.acpi sysctls) in the hope the provide something usefull. http://people.freebsd.org/~barner/cx/ --=20 Best regards / Viele Gr=FC=DFe, barner@FreeBSD.= org Simon Barner barner@gmx.de --cWoXeonUoKmBZSoM Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFHNBbLCkn+/eutqCoRAn9PAJ9zhgK84iy+ijg4TDHw/QOW8GKd3QCgnm07 lBhYpFEVo7RZeKSa0RTiI4o= =sEy6 -----END PGP SIGNATURE----- --cWoXeonUoKmBZSoM--
