Device.hints is a dangerous thing to play with. All device.hints should give you is your console back if you are missing it. Do you mean hard hangs on reboot such as after you do a shutdown -r now the system shuts down, tries to reboot, and then just stays black and never boots? >> > Perhaps the legacy stuff needs to be backed out or disabled pending fixing? >> >> Well, the problem here is that ACPI isn't working, not that legacy is broken. >> What legacy does is make it so that if we try to use ACPI, we actually rely >> on it to work.

Suspend/resume, power shutdown, etc. That's like saying that PAM works if all the programs that use PAM automatically fall back to reading /etc/master.passwd manually and complaining that people broke things when they removed the ability to read /etc/master.passwd manually thus revealing the inherent breakage in PAM. (Just in hypothetical terms.) Iwasaki-San's patch adds back in the only part of the extra "bogus" stuff that legacy took out that could have an effect on your system with respect to PCI. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
