Public bug reported:
Hi all,
I have a laptop of samsung with the model number NP-Q35K001/SHK.
I have install ubuntu 7.10 x86 version and found a problem as mentioned below.
Steps.
1) Booted the machine in Ubuntu admin account.
2) Do SUSPEND( by clicking the power on/off button,placed top right corner).
3) Switch on the machine to wake up from the SUSPENDED mode.
4) Do RESTART( by clicking the power on/off button,placed top right corner).
The machine freezes after sending terminating signal to all. I have to
do hard reboot then.

More over i tried to narrow down the bug as follows.
1) Boot in to the recovery mode (in the single mode).
2) Run the following command to suspend the machine.
/bin/sh /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
3) Press the power on/off button to resume from suspend mode. It comes up
successfully but with some error like.
FATAL: Module acpi_sbs not found.
I tried to find out if the module acpi_sbs has been loaded or not by
checking lsmod command. I didn't find any such module.
4) Then fire the command "reboot". As i mentioned the machine hangs up after
sending all process terminating signal.
I got the last message as [[xxx.xxx] Restarting system]
Please let me know if any other info is required.
With regards,
Samarjit
