The machine is a fujitsu S710 laptop running: FreeBSD 10.0-CURRENT #4 r237339=e61ad3a-dirty: Sat Jun 23 17:12:58 CEST 2012 I did the tests in the following conditions: - No X running. Everything in console. The machine has an Intel video card, but I did the tests without the i915kms module. - I removed all the modules I could from the kernel. The behavior is basically the machine seems to suspend fine (I see the power led blinking) but when resuming it freezes hard. I see the disk spinning for a while and then it stops. I can't ssh to it, I can't use the keyboard at all so I can issue no command at all. I've tried stripping down the kernel (everything is out except if_ath, em and usb stack). No pccard, no sdhci, no sound, no cuse4bsd, no usb hid devices (I'm using uhidd for hid devices), no acpi_video or acpi_fujitsu there but the same result. I tried enabling debug.acpi.resume_beep=1. When doing this, the laptop beeped like crazy. I tried using the serial console on the laptop. I saw the suspend process taking down some usb devices. Resume showed nothing on the serial console. With sysctl debug.acpi.suspend_bounce=1, the machine stayed alive (this is expected) but the screen went blank (this I think isn't expected). The video never came back. The three-finger-salute rebooted the machine. With acpi.reset_video I got no result. Disabling devices in the BIOS (removing wifi, bluetooth, webcam, etc ...) didn't bring me further. -- --------------------------------------------------------------------------- Prou top-posting : http://ca.wikipedia.org/wiki/Top-posting Stop top-posting : http://en.wikipedia.org/wiki/Posting_style O O O Gustau Pérez i Querol O O O Departament d'Enginyeria Telemàtica O O O Universitat Politècnica de Catalunya Edifici C3 - Despatx S101-B UPC Campus Nord UPC C/ Jordi Girona, 1-3 08034 - Barcelona _______________________________________________ freebsd-acpi@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscribe@freebsd.org"
