Bug Description

Shortly after booting, the kernel 2.6.15-18-amd64-generic crashes on my computer. I get the following message:

early exception rip
ffffffff802294d9 error 0 cr2 ffff810040000000 (acpi_table_compute_checksum)
ffffffff8011df9a error 0 cr2 ffffffffff5fd023 (safe_smp_processor_id)

(I looked for the function names in the

I tried to boot with acpi=off, -noapic, -nolapic and got the same error. The kernel crashes exactly the same way with both the live and the install cd (which is not surprising). I have:

cpu: AMD Athlon 64 3000+
chipset: nvidia CK804 (nForce 4) + AMD k8 bridge
ram: DDR200 1go

I have been running breezy for a while, without a problem. I also tried to boot with the -k8 kernel and got the same result. I'm trying to boot on a custom kernel without smp and acpi.

Can you get me a photo of the screen when it crashes? Also, make sure to remove the "quiet" boot option so that as much output is created as possible.

The kernel crashes at the very beginning of the boot. Here exactly what I get on the screen (without the "quiet" option):

I disabled SMP and ACPI in the kernel and it booted. So it's possible that the problem is related to that.

I also tried with earlyprintk=vga, and it seems that the kernel after mapping the BIOS-provided physical RAM map. I searched about this issue on the web and didn't get much luck, but I noticed some changes in 2.6.16 around SMP. I'll give it a try tomorrow.

Can you attach a full dmesg from the working kernel? Does the generic kernel boot with nosmp?

kernel command line:

So 2.6.15-20-amd64-k8 doesn't work? Note, this is the kernel I am using on my AMD64-3200, with nvidia4 chipset (not using ATI video like you are though).

Yeah, I've just tried again after coming back from work and I still have the same issue with 2.6.15-20, -generic and -k8. Just to be sure, I tried to plug my old nvidia card, with no luck. I have searched on the internet for similar problems, and it seems to be quite rare. With nosmp and acpi=off on the command line, everything works perfectly, though.

I'm experiencing this bug also with the latest 6.06 beta live cd. nosmp and acpi=off work for me.

I had the very same problem on an IBM x326m 7969-67Y, which is a dual opteron 275.

Removing the Remote Supervisor Adapter II fixed the boot problem. The card is what IBM calls a Baseboard Management Controller, an MS-9549 PCI card. However, then fan controll stopped working :-(

I seem to be having some problems with iommu too, and when enabling earlyprintk=vga it stops right after having complained about not having an aperture.

Thanks for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.
