Mitsuru,

Thanks, it works. I was able to boot without panic with your patch. 
Sorry for not getting back to you on the acpidump and debug info as I 
didn't have my null modem cable and notebook with me to use as a 
serial console. Do you still need to acpidump files? 
BTW, I did notice some hangs that possibly related to ACPI. About two 
or three months ago, this ASUS CUSL2 hang while running sysinstall. 
It can react to Alt-F?(i.e. switch virtual console) but not on any 
other keys nor responding to ping from another computer. I was not 
able to isolate the cause until this time I unset acpi_load. Without 
acpi.ko loaded, I could run sysinstall with no problem. In fact, I 
just found that loading acpi.ko also have the same freeze with CUPS.

What should I do to help identifying if this is ACPI related?

Regards,
