back on Grandpa issues

from his computer dmesg:
Malformed early option 'acpi'
I will discuss this one on a separate thread, because don't want hijack this thread.
DMI: Gateway DX4720-03/MS-7399, BIOS A7399NG2.202 08/06/2008
That's the current installed BIOS version, there exist an update but refer explicitly to CPU Q8200, I think it would not be beneficial here:
http://support.gateway.com/us/en/product/default.aspx?tab=5&modelId=2287Kernel command line: apm=off acpi=off mce=off barrier=off ide=nodma idewait=50 i8042.nomux psmouse.proto=bare irqpoll pci=nommconf BOOT_IMAGE=PClinuxOS_2012.2 root=UUID=9b10f7c2-e1ce-4d55-bc27-e900b6849be2 splash=verbose nokmsboot vmalloc=256M pci=nommconf acpi=on resume=UUID
the kernel parameters actually in place (this was from "safeboot" selection)
Misrouted IRQ fixup and polling support enabled
This may significantly impact system performance
One of the parameters,
irqpoll ?, is properly recognized but note that this will affect overall performance.
there are a few entries like this, don't know it this is a fix or a bug.
pci 0000:00:03.1: PME# supported from D3hot D3cold
pci 0000:00:03.1: PME# disabled
Googling around it seems that the machine do have some issue around
apic, but it's not visible right now.
Grandpa,
edit your /boot/grub/menu.lst and add as last three stanzas the followings: (use copy & paste)
title TEST-NOLAPIC
kernel (hd0,4)/boot/vmlinuz BOOT_IMAGE=TEST-NOLAPIC root=UUID=9b10f7c2-e1ce-4d55-bc27-e900b6849be2 splash=verbose nokmsboot vmalloc=256M resume=UUID=4d65bcd3-0be1-49e9-b9d5-9fb09f4749a5 vga=788 noapic

save, reboot, test all new entries one at a time, if you are able to boot, post again the file
/var/log/dmesg
