reboot command not really rebooting...

[brain salad surgery]

can somenone tell me why on my compaq armada m700
with kernel 2.6.11-gentoo-r6, when i type reboot,
the system is not really rebooting nor halting...
it hangs somewhere after having closed the services
and i have to power it off and on manually

i'd really like to make a router of it and to be able to reboot
it remotely

thanks

You have to set APM or ACPI under your kernel's config. They manage the halt/reboot.

of course, i have set acpi directly in the kernel that i uses successfully
for the sleep state and all, with acpid running. Maybe is it
acpid that has to be set properly ?

here are the relevant parts from my kernel config:

#
# Power management options (ACPI, APM)
#
CONFIG_PM=y
CONFIG_PM_DEBUG=y
CONFIG_SOFTWARE_SUSPEND=y
CONFIG_PM_STD_PARTITION=""

#
# ACPI (Advanced Configuration and Power Interface) Support
#
CONFIG_ACPI=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_VIDEO=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_IBM is not set
# CONFIG_ACPI_TOSHIBA is not set
CONFIG_ACPI_BLACKLIST_YEAR=0
# CONFIG_ACPI_DEBUG is not set
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y
CONFIG_X86_PM_TIMER=y
# CONFIG_ACPI_CONTAINER is not set


#
# APM (Advanced Power Management) BIOS Support
#
# CONFIG_APM is not set

#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=y
CONFIG_CPU_FREQ_STAT_DETAILS=y
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_TABLE=y

There are few things that could interfere:
- CONFIG_PM_DEBUG should be unset
- if you set CONFIG_SOFTWARE_SUSPEND, you should provide a partition for it under CONFIG_PM_STD_PARTITION="". Note that it must be around twice the real memory equipped on your box.
The rest seems quite OK.

BTW brain salad surgery, the halt or reboot are normally managed by the kernel. The acpid is just a relay. To be sure that your kernel is able to do it without being annoyed by some services messing around a simple program is always welcome:
fast_reboot.c

[brain salad surgery]

thanks,

could you explain why fast_reboot this would bypass services shutdown ??
anyway, this did not work any better...

i've recompiled my kernel removing
- CONFIG_PM_DEBUG
- CONFIG_SOFTWARE_SUSPEND,
now using the reboot command stops
each of the opened services and
i even see the message:
Restarting system.
Right after, the screen comes black
and the damn hard drive led
stays on 30-60sec, then nothing.
i have to power off and on manually

Do you think the system has really
rebooted (right after the restarting
system message) and have
instead some problems at boot
(before lilo) ? It's difficult to tell...

I've checked in the
bios but haven't seen anything related
(bios for laptops are quite different
and this is my first one)

Had similar problem on a Toshiba Tecra M2 notebook, do you have ipw2200? I had to rmmod it explicitly (after bringing interface down) to make reboot work.

[brain salad surgery]

nope, no ipw2200 driver implied here...

thanks i'll try to remove the acpi options i don't need.

i was wondering if a command such as fast_reboot
is safe for partitions (if they are really unmounted ok
in the process). If so, i could think of a similar fast_halt
command that i could use on my server (not my laptop).
It has a big raid 5 partition that i really don't want to loose
(about a teraB). Anyway, the system is protected
with a tripp-lite ups that won't last more than
a few minutes (<5min).

a fast halt command would then be useful to be
sure the system halt even if, say, mldonkey
would make some troubles while stopping and
hang... Just want to be sure it is safe
for my partition md0

for a halt, what would be the fast_halt.c i
would need ?

i'll recompile my laptop's kernel...

thanks a lot guys,

[brain salad surgery]

just to be sure: the fast_reboot program didn't work

and without

CONFIG_ACPI_SLEEP
CONFIG_ACPI_SLEEP_PROC_FS

the kernel doesn't do any better

would like to know why...
a bios issue ? anyone's got a compaq armada m700 ?

[dgaffuri]

Have you tried to play with reboot= kernel parameter? I don't remember exactly the allowed values now.

[DiD@SyN]

try using ACPI OR APM. In your case, I would say disable all APM options in your kernel. If you really need APM support try disabling all ACPI options.
Give it a try.

thanks a lot guys, i'm happy to have that
much suggestions

only acpi is set, and i did give a try to apm without success
(and moreover sleeping state wasn't well supported, so
i switched back to acpi)

i'm pretty sure now that the system has really shut down
using the reboot command and is having trouble booting
because i hear the cdrom make a little sound

i trying all of the reboot kernel parameter using
a line like:
append="reboot=h"
but none of them changed anything...
the system still hangs on a black screen before
lilo and before i can read "COMPAQ" like in a
usual boot process

[brain salad surgery]

i tried recently a live cd (WHAX) that was able to
reboot the laptop, no problema !

but the fast_reboot script is not able.

someone has an idea ? Another kernel option
that conflicts ?

[pem]

You could check if this livecd relies on APM instead of ACPI. May be your laptop is not compatible with ACPI. That would explain a lot. If this is the case, you will have to remove everything concerning ACPI and validate every options for APM.
