hardlocks in 8-CURRENT
Matthias Apitz
Hello,
If you go with your laptop to some meeting, you just take it with you and
normally not even the power-supply; when you return to your desk, normally
you put your laptop on the table, plug-in power and open the lid...
from time to time I encounter that the laptop after opening the lid is
just locked, i.e. hardlocked and does not even respond on ping from other
places; I did tests to see when it crashes, i.e. if it is based on the
movement, of WLAN AP re-connect or whatever; I now always first open it, work a
while across WLAN and then plug-in the power; the lock occurs only on
the plug-in of the power-supply;
any idea what to do next for debugging this? thanks
matthias

Hello Peter,
Thanks for your reply;

do be more exactly: it is a 8-CURRENT based on CVS checkout from end of
May 2009;

this is at the moment no option because it is my laptop to do real work
all day;

When the lock occurs I'm in X11 (KDE 3.5.x); the only key which works is
pressing power-button for some seconds, i.e. full power-off;

Is this to be done in rc.conf or via sysctl? I have nothing set about
acpi_throttle;

OK.

Can you try switching to a VTY0 before connecting power and see if
anything shows up.

acpi_throttle would be enabled in the kernel config or via kld.
Power management is enabled with something like the following in rc.conf:
powerd_enable="YES"
performance_cx_lowest="HIGH" # Online CPU idle state
performance_cpu_freq="HIGH" # Online CPU frequency
economy_cx_lowest="LOW" # Offline CPU idle state
economy_cpu_freq="LOW" # Offline CPU frequency
>What else would be handy?
Hardware details, output from sysctl's dev.cpu and hw.acpi, dmesg,
output from kenv. If possible, dev.cpu.*.freq just before it hangs (I
realise this may be difficult).

Firstly, 8-current means you're running a build more than 3 months old.
Have you considered upgrading?
When the lockup occurs, are you in X11 or on a VTY? If the latter, is
there anything relevant on the console? Does the keyboard work at all
(Caps-lock and/or Ctrl-Alt-ESC)?
What (if any) power management are you running? Do you have acpi_throttle
enabled - if so, you could try disabling it.
Finally, some more details of your system would be handy.

What type of video adaptor is in your laptop? (I have a Radeon in mine,
and have occasional lock-ups just trying to start X if I have DRI
enabled. Come to think of it, whether or not you have DRI enabled in
your xorg.conf might be relevant, as well. IIRC, it's generally enabled
by default.)
Peace,

I think that it's not expected for CURRENT to be very stable and it's
more less expected that you are able to follow current because sooner
or later you'll have problems like the one you have. I suggest you
run STABLE.
That aside, hardlocks are hard to debug, specially while on X. My
first try would be to remove drivers one by one.

Matthias,
just a shot in the dark, but I bet keying "res" ENTER (w/o the quotes)
in while your system seems to be dead will give you 'back' (well, kind
of) your system. Can you try that the next time, please?
If that works (reboots your system) we can see if you're able to get a
core dump out of your box.

Some days ago I catched this (or better: I was catched by this) while
still in ASCII mode short after the re-boot. There was no message on the
screen and keying "res<ENTER>" did nothing, not even any char of "res"
was echoed.

We can close this issue, it is not FreeBSD related. Today morning I
plugged in the power while the laptop was still in pre-boot menu to
choose between FreeBSD and Vista partition, and this menu was locked as
well and no other ways as power-cycle to bring it up again.
I will contact Dell.
