PANIC: Fatal Exception "NMI Interrupt" occured

Reported by: MasterNetra Owned by: mmlr
Priority: normal Milestone: R1

Description

At bootup I get this after after dot load: Panic: Fatal Exception "NMI Interrupt" has occured. Error code: 0x0 (I think I got it as displayed, had to memorize it)

These "should" not happen. That's a so called non-maskable interrupt. You should be able to type co[ntinue] at the KDL prompt. Does that work?

comment:2 by MasterNetra, 10 years ago

Actually yes it does.

comment:3 by stippi, 10 years ago

Cool. I am not sure, but IIRC, the NMI panic is kind of a warning, and we may be able to just ignore the NMI. But kernel devs would know this stuff much better than myself.

comment:4 by vodoomoth, 9 years ago

Hope I am not hijacking this ticket but I came to report the same 'PANIC: fatal exception "NMI Interrupt" occurred! Error code 0x0' error and did a search first.

This happened after I inserted the R1Alpha2 (not alpha1 as was the case for the original poster) CD in my laptop in order to install Haiku to a partition created with GParted. That same laptop which will also receive FreeBSD 8.1 and Ubuntu 10.10 in the coming days also features a freshly (re)installed Vista SP2.

Laptop: Fujitsu Siemens Amilo Xi2528, 2 Ghz Core 2 Duo, 2x250 GB HDD (freshly unRAIDed), 2 GB of RAM. This 2008 laptop can't boot any bootable CD from my external DVD drive although it boots from USB keys...

Anyway, I followed the 'press shift for fail-safe mode' tip but the message is the same. I also used "co[ntinue]" as offered by @stippi: command unknown. I ended up using "continue" but this got the PC locked: Ctrl+Alt+Del does nothing and doesn't reboot. Will wait for the next release.

comment:5 by Duggan, 8 years ago

I have this problem as well. I have an HP Pavilion dv6000 series (not sure the exact number) laptop with a Core2 Duo processor. This has been a problem for me as long as I've been booting on native hw. Pre-A3 the NMI occurred after the 3rd icon lit up on boot, post-A3 it now occurs before the first icon lights up. Typing 'es' works and the NMI only pops up once. I'll get a syslog posted up in a day or two and I'll try to hunt down the exact revision where the time the NMI happens changes.

Most probably due to the IO-APIC changes. The IO-APIC isn't causing it, but causes the PCI module to be loaded and initialized earlier in boot which probably triggers this. In either case a syslog would confirm.

I'm going to generalize this ticket to NMI (presumably at PCI init time) so that it can more easily be found. I'll also try to look into it, but can't really promise anything as I can't reproduce the issue over here.

(In #8097) I'm going to close this as a duplicate of #4555, which I just made more general so that it can more easily be found. The stacktrace in this screenshot clearly points at PCI init, so this helps already narrowing it down.

Hey mmlr, I attached a small snipet of my syslog confirming that it's PCI related. If you want the entire syslog let me know and I'll try to get a clean one up soon.

That's fine, the attached one is great, no need to dig further for now. I've browsed through the PCI specs to see if there was anything obvious and saw that the parity error handling might be to blame, as that one can be configured to trigger an SERR assert that'd lead to the NMIs. Though even if that was the case we'd still need to investigate/fix the reason for the parity error in the first place. Also SERR may be asserted in other situations, like incompatible transactions (as in lower bit width busses that can't complete input addressing) or other errors. We might not account for things like that, but I haven't yet looked into our code to check.

Change the order of error clearing and enabling error reporting.

comment:11 by mmlr, 8 years ago

Can you please try the attached patch and see if that gets things going? Basically it causes error conditions to be cleared first and only then enables error reporting on the PCI bridges. This may avoid reporting for still pending errors at configuration time that could lead to the NMIs.

comment:12 by Duggan, 8 years ago

Sure :) I'll do that a little later today. Is that a proper fix? I don't know alot about this stuff, but should those errors be handled? Anyway, I'll let you know how it works. Thanks!

comment:13 by Duggan, 8 years ago

Nope, that didn't do it :/

in reply to:  13 comment:14 by mmlr, 8 years ago

Replying to Duggan:

Ah well, at least that means it's not just some lingering error condition that triggers as soon as error reporting is enabled (or that our error reset doesn't actually work). I guess some more debug output is needed to determine what's going on exactly.

In either case the error condition seems to come from the PCIe port that has the wired ethernet controller attached (PCI device 28 function 5 with secondary bus 8). From the data available alone it doesn't really look any different from the other PCIe ports...

That reminds me though that the error condition clearing only every uses kprintf to output the data to the kernel debugger. What you could do when the NMI kicks in is execute the "pcistatus" KDL command, which should then list any present error conditions before trying to clear them. If you could attach that output (you can simply continue after executing that command) as well, that might give some clue.
