Public bug reported:
Running Edgy Eft (6.10) with all updates as at Oct 21 2006. Kernel is
2.6.17-10.33.
System is HP Compaq nc6320 notebook.
To reproduce the problem:
1. Boot Ubuntu either in normal mode or single user mode.
2. Perform a standard clean shutdown.
Symptoms:
1. When you next power up the computer the BIOS seems to take approximately
twice as long as normal to reach the stage where BIOS password is entered.
2. If you try to enter the password, the BIOS seems as if the it doesn't accept
input from the keyboard. Also note that the preceeding F9 (for alternate boot
device) or F10 (for setup) are also ignored.
3. Also note however that Fn-F9 and Fn-F10 which provide hardware control of
screen brightness does still work.
4. Powerdown/restart with Power button does not recover problem
Workaround:
1. Once the problem occurs, the only way I can boot my computer is to remove
plugpack power and to remove the LiIon battery for a few seconds. Restoring
power then allows me to boot the computer normally.
Testing for Possible cause:
1. If rather than performing a clean Gnome shutdown or "shutdown - h
now", I simply hold the power button down I can restart the computer
normally. This would indicate that the shutdown process is leaving
something in a state which prevents the BIOS from allowing the computer
to restart.
2. When the computer tries to start BIOS after the clean shutdown it
takes twice as long as normal. I am wondering whether some soft
"firmware" is left in a state that prevents BIOS from properly
initialising the hardware.
This laptop is new, and does not exhibit the problem when shutting down
from running Windows XP.
