[Bug 116752] Re: NMI received for unknown reason a0 on CPU 0
Albert Cardona, 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 test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

David, thank-you for that revelation. That indicates that the Bluetooth device-driver might not be doing everything it should when handling the PM suspend event, or it might be that the hardware is doing something unexpected that is probably handled as a quirk in Windows drivers (I assume the same doesn't affect Windows?).

[Bug 116752] Re: NMI received for unknown reason a0 on CPU 0
NMI is non-maskable interrupt. It is usually caused by a memory parity
error.
The obvious question is, has the memory been thoroughly tested or
alternative known-good modules been tried. The linkage to devices tends
to indicate RAM is fine but it would be good if we could authoritatively
rule it out.
The alternative is that the devices are somehow messing with the system
bus.
The kernel handles it in
arch/x86/kernel/traps.c::mem_parity_error():
{
printk(KERN_EMERG
Uhhuh. NMI received for unknown reason %02x on CPU %d.\n,
reason, smp_processor_id());
printk(KERN_EMERG
You have some hardware problem, likely on the PCI bus.\n);
#if defined(CONFIG_EDAC)
if (edac_handler_set()) {
edac_atomic_assert_error();
return;
}
#endif
if (panic_on_unrecovered_nmi)
panic(NMI: Not continuing);
printk(KERN_EMERG Dazed and confused, but trying to
continue\n);
/* Clear and disable the memory parity error line. */
reason = (reason 0xf) | 4;
outb(reason, 0x61);
}

I found this LKML commentary from 2003.

Re: [Bug 116752] Re: NMI received for unknown reason a0 on CPU 0
Hi, As far as I'm concerned, that error didn't appeared since Hardy Heron on my laptop (Acer Aspire WSMI 1802 / 1800 series). And it never appeared with my other pc's (ranging from old Pentium II / III and recent Core2Duo's). I remain convinced (imho) that the cause was not purely kernel related, but rather a combination of hardware / drivers hiccups. In the time I signalled the problem, I could almost certainly provoke it by using compiz (advanced effects) / firefox and that on my P4 / ATI Radeon mobility (X600) video card base laptop. (Note: with the free Radeon driver as with the non free fgrlx driver made no difference). Deactivating compiz did vastly reduced the occurence of the error. At that time Compiz was also far least stable has it has become... it may also be related, although it was certainly not the only cause for deactivate it only reduced the frequency of occurrence of the error.

Thanks for the update Nick HS. The kernel in intrepid-proposed sounds promising then. Can anyone else test the 2.6.27-10 kernel in intrepid- proposed? @Albert Cardone, since you are the original bug reporter, I'd be particularly interested in hearing back from you. To test the kernel in intrepid-proposed do the following: 1) cd /etc/apt/sources.list.d 2) create a file intrepid-proposed.list which contains the following two lines (sudo vim intrepid-proposed.list): deb http://archive.ubuntu.com/ubuntu/ intrepid-proposed main deb-src http://archive.ubuntu.com/ubuntu/ intrepid-proposed main 3) sudo apt-get update 4) sudo apt-get install linux-image-2.6.27-10-generic 5) sudo rm /etc/apt/sources.list.d/intrepid-proposed.list 6) sudo apt-get update Steps 5 and 6 basically undo the enabling of intrepid-proposed. Of course you'll finally need to reboot into the 2.6.27-10.20 kernel to test. Please let us know your results.
