This was happening before 1.8 and also happens with a UP kernel.

No this only happened with 'options ACPI_DEBUG' in my kernel config
file.

Thanks,

I feel relieved to hear that somehow ;) I saw a similar problem on
some of PCs around, but disable_on_poweroff always worked. Does updating
BIOS fix it?

I recommend against compiling acpi driver in the kernel.

I believe I know it. In short, don't use that option, and build acpi
driver with an environment variable ACPI_DEBUG set to yes:
cd /sys/dev/acpica5
export ACPI_DEBUG=yes
export CFLAGS='-O -pipe -DSMP=1' (only for SMP kernel)
make obj && make depend && make && make install

The problem is that you used an option which only applies to acpi driver
compiled in the kernel, but if you build the kernel by buildkernel or
nativekernel, that option gets propagated to module build without adding
necessary files. When you reboot your laptop, acpi driver fails to
load because of missing symbols which are supposed to be defined in those
missing files. If this is the case, /var/run/dmesg.boot should contain
the clue.

Cheers.

I updated to the latest BIOS from Toshiba and there is no change.

That's too bad. Can you try to see if `acpiconf -d' also locks up your
laptop. What it does is call acpi_Disable() to transfer the system into
legacy(non-ACPI) mode, and this function is also called when you reboot
it, or try to shutdown with hw.acpi.disable_on_poweroff=1. You'd better
try this in single-user mode to avoid fsck in the next boot.

Cheers.

I do not get a lock-up with 'acpiconf -d'. Though lock-up doesn't
seem like the correct term. With hw.acpi.disable_on_poweroff=1
a 'shutdown -h now' shuts down the laptop as usual but at the "Press
any key to reboot..." message I must press and hold the power button
to power off the laptop. With hw.acpi.disable_on_poweroff=0 a
'shutdown -h now' shuts down the laptop and a single tap of the power
button powers off the laptop. I seems like the laptop goes into
suspend mode rather than actually powering off the hardware.

Joe

Does this still happen? Is this relevant to anyone?

Hi.
If you still have access to the laptop M115-S3094, can you confirm that
the problem (can't power off using shutdown command) persists or not?
