My laptop has a T4400 CPU and arch64,when it had 2.5G ram,worked fine.
when I add RAM to 4G ,my laptop always restart when booting.
then,I found that if I turn off acpi on grub.cfg,it could boot.
I can't find any error on log.
I tried to install 64bit opensuse 11.4,it has the same problem.
and I also installed 32bit arch,it can boot up normally.
Is that my laptop problem? or I should rebuild the kernel and change some config.
maybe a bios bug??
I could not use any hotkey on my keyboard,such as turn off the webcam.That would restart the laptop.

Possibly mismatched RAM sticks? Have you run "memtest" from a Live Linux CD (or UBCD) to check the RAM itself?

Thanks for reply.
I have tried Memtest ,it shows no problem.
and my two RAM sticks are same,at least the hardware test tool shows that.
I could boot into Windows 7,with PAE Patch I could use 4G totally.
arch(32bit) show more than 3G RAM,and apci could run.
I don't want to go back to use 32bit and reinstall all app.
forgive for my poor english...

I found something new.
"acpi=off" can boot up but "acpi=ht"
it's said that "Try booting with "acpi=ht": This disables all of ACPI except just enough to enable Hyper Threading. If acpi=off works and acpi=ht fails, then the issue is in the ACPI table parsing code itself, or perhaps the SMP code."
