Asus N90sc Notebook does not boot without pci=noacpi, nolapic or acpi=off bootoption [Maverick]

I think I'm seeing the same bug. Reboot, panic or hang a few secons upon kernel loading start. Both acpi=off or nolapic work (but not noapic).

This is in a computer which runs fine in 10.04. Booting 10.10 with either of these, htop and system monitor only shows only one of the four cores (all are shown in 10.04).

I'm using the final 10.10 image for the netbook edition.

CPU is an i5 650. I'm going to run the apport-collect next. The CPU, from lshw, is:

Just tested with current mainline kernel and behavior is the same (boot with acpi=off, nolapic, reset otherwise).

Kernel was linux-image-2.6.36-999-generic_2.6.36-999.201010120905_i386.deb

I found a much better workaround for me:
bootoption: "pci=noacpi"
This turns off acpi recognition during pci detection.
And now, everything is fine. (2 cpus, frequency scaling and battery/energy management works perfectly)

pci=noacpi doesn't work for me.

Tried production 10.10 image on an AMD P920/AMD SB700/SB800 system and it absolutely required pci=noacpi or acpi=off in kernel option to boot up successfully.

Tried again with Natty alpha 1, which is kernel 2.6.37. Won't boot with default options; it will boot with nolacpi but not with noapic, and in any case only one CPU is seen...

Just found that passing nolapic_timer option also works, and this keeps the four CPUs visible. Tested in Maverick and Natty. Not sure about the implications of this option though.

Tested alpha 2 of Natty. Boot will reset as before with stock (no) options. With nolapic_timer or nolapic, it continues, shows splash screen, and later on enters an infinite loop reporting some kernel panic. At least that's what it seems to be, since it flies by too fast, but I can see mention of registers.

I have the same problem on an asus x90s under natty.
It boots with nolapic (but one cpu is missing) or acpi=off (but no battery managment and the special jeys won't work). pci=noacpi has the same effect as acpi=off.

After some test it seems that pci=noacpi allows the use of battery managements but the notifications comes with a delay of 5 to 20 seconds...

tankdriver, thank you for reporting this bug and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
