https://bugzilla.novell.com/show_bug.cgi?id=436384 User matthias.andree@gmx.de added comment https://bugzilla.novell.com/show_bug.cgi?id=436384#c3 --- Comment #3 from Matthias Andree 2009-01-29 08:38:32 MST --- Well, the openSUSE 11.0 system was eaten by a disk hardware fault; I'm going to replace it by 11.1 soon (I kept only /etc and /var in the backup, not /usr); I'm currently running off FreeBSD 7.1 that survived on the second hard disk drive, for lack of time. Interestingly, FreeBSD exhibited a similar regression between 6.3 (or perhaps early 7.0 (pre)releases) and 7.1. FreeBSD 7.1, too, fails most of the time to shut down the system. Setting hw.acpi.handle_shutdown in FreeBSD helps for (estimated) half of the time, whereas shutting down to legacy mode does not seem to help. See http://www.freebsd.org/cgi/man.cgi?query=acpi&apropos=0&sektion=0&manpath=FreeBSD+7.1-RELEASE&format=html I also have a vague feeling that something during ACPI initialization or operation (perhaps acpid attaching/configuring the firmware or similar), or perhaps X11/ACPI interaction, trigger this issue; it's just a feeling, but shutting down FreeBSD from single-user boots works reliably in either setting, and seemed to help a bit with openSUSE 11.0 as well. Question: do Linux and FreeBSD share ACPI code and/or updates? Followup-Question: is that my BIOS at fault or an ACPI regression shared by Linux and FreeBSD? I presume I'll have to dig out some more debug information from either system, and I'll do that ASAP. Is there an easy way in 11.1 to "tee" the console logs out across Ethernet or dump them to swap, or delay after messages, or copy to a slow serial console at 1200 Baud? That might help capturing the messages in case the monitor blanks too quickly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Question: do Linux and FreeBSD share ACPI code and/or updates? Yes. So your report that BSD also broke is interesting. It seems the problem

But please first try out 11.1. If it's still not solved there, you should try the latest .29 kernel. We will provide a binary rpm for the latest kernel soon. We shouldn't waste time on things that may already be solved. If it's not yet solved, you already gave a nice hint where to look at.

Followup-Question: is that my BIOS at fault or an ACPI regression shared by Linux and FreeBSD? Hard to say. Maybe both. As it already worked it definitely looks like a kernel regression. Even if it was a bad BIOS it could handle, it should still be able to do so.

I am setting the bug to need-info for you. Remove the flag as soon as you have tested 11.1. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
