In fact I forget how I worked out that it worsened in 2.6.early. google(noapic) gets 232,000 hits. I don't think it really matters when or why it happened. If we take the approach of fixing one machine at a time, we'll only need to fix a few individual machines to improve the situation for a lot of people.
> I don't know. In fact I forget how I worked out that it worsened in > 2.6.early. > > google(noapic) gets 232,000 hits. is there a way to ask google "only stuff in the last year"? Asking because "noapic" in 2.4 was the standard "try this" answer when people had a bios that had busted MPS (but good ACPI)... > I don't think it really matters when or why it happened. well to some degree it does; if it's one patch causing it narrowing it down at least somewhat in time would help ;) > If we take the > approach of fixing one machine at a time, we'll only need to fix a few > individual machines to improve the situation for a lot of people. alternative is that more new machines showed up that need it somehow, eg not really a regression just something else. Different approach is needed for hunting that down. But to be realistic we need to narrow things down a bit, which means 1) Only care about SMP machines. APIC on true UP (no Hyperthreading/Dualcore) is a thing no hardware vendor tests (Microsoft doesn't use it) and is just too likely to trip up SMM and other bad BIOS stuff. * exception is probably people who don't WANT to use apic but where it somehow gets used anyway; if that happens we probably have the magic bullet that causes the regression :) 2) Only care about ACPI using kernels. Non-ACPI uses MPS tables for this, but most vendors hardly maintain those anymore at all and they are generally just /dev/random nowadays 3) Ignore overclocking; if you overclock using the FSB the apic busses run out of spec as well; can be a huge timewaster in debug time.

Some APIC-related bugs in the kernel Bugzilla that have been reported or confirmed during the last 12 months (I only looked at "apic" in the subject, there might be more related bugs in the Bugzilla): #5038 Fast running system clock with IO-APIC enabled #5303 AMD64 Erratum: Should not enable C2 when using APIC #5565 Guess of i386 APIC PTE area scribble #6404 APIC error on CPU0: 40(40) #6748 Clock drifts by 30% for SMP kernel w/APIC #6859 Linux kernel won't work without "nolapic" passed #6890 Kernel boot freezes when APIC is enabled & SATA is used > > I don't think it really matters when or why it happened. > > well to some degree it does; if it's one patch causing it narrowing it > down at least somewhat in time would help ;) > > > If we take the > > approach of fixing one machine at a time, we'll only need to fix a few > > individual machines to improve the situation for a lot of people. > > alternative is that more new machines showed up that need it somehow, eg > not really a regression just something else.

Although they share 4 letters they're entirely different animals. > #6890 Kernel boot freezes when APIC is enabled & SATA is used seems to be UP as well but asked for confirmation in the bug (lack of lots of information here!). If this isn't UP this could be the first real case of "noapic" in your entire list...... which isn't too useful.

Really. On newish machines (and that is 7 years old or newer) MPS tables are NOT getting much if any attention by the bios guys. So Linux should use ACPI, and if you deliberately disable ACPI and THEN hit a problem to a large degree you asked for the problem in the first place. Older machines, different story.

We KNOW it can't work on a sizable amount of machines. This is why it is a config option; you can enable it if YOUR machine is KNOWN to work, and you get some gains. But it's also understood that it often it won't work.

Even on my cheap Asus board running an i386 > AMD Athlon XP with 1.8 GHz the APIC is both used and working without any > problems. "it works on my one machine so it works for everyone". That's simply not true. We KNOW it can't work everywhere on UP, especially on i386. SMM assumptions; people gluing the apic pins to the reset line, we've seen it all. That it works for you is great. But that doesn't mean it automatically works for everyone.

So yes you're right, that nowadays is a pretty large group. But it's the safe group I guess:)

But it's the safe group I guess:) But if APIC is even used on my more than 1 year old 40 Euro Socket A board (AFAIK there have never been dual core Socket A processors, there were no Socket A hyperthreading CPUs, it's not an SMP board, and the VIA KT600 is not an SMP chipset) it's not in what you call "safe group", and I don't see any reason why my board should behave different in this respect from all of the millions of other UP Socket A boards. Googling show that it could be that your claim "APIC on true UP (no Hyperthreading/Dualcore) is a thing no hardware vendor tests (Microsoft doesn't use it)" earlier in this thread was wrong. Looking at e.g. [1], it seems Windows does use the APIC even on UP. cu Adrian [1] http://www.microsoft.com/whdc/system/sysperf/IO-APIC.mspx
> But if APIC is even used on my more than 1 year old 40 Euro Socket A once sparrow does not a summer make. now can we get constructive again. If you find a real case where noapic is needed on an SMP machine, preferably one where it wasn't needed before earlier in 2.6, let us know; it's worthwhile to chase those down since we know it's a decent use case and it's not flaky hardware.

I actually agree here. Linux needs to be easier for people to use, not harder. Isn't there a way for bootloaders or the kernel early on figure out if the machine supports SMP, and if it doesnt, load a uniproc kernel instead? > > > You miss my point. > > > > > > You said you'd suspect it to be turned off automatic most of the time, > > > and that's the point I think you might be wrong at. > > > > it won't be turned off on machines that support dual core processors > > etc, since those DO get validated and designed for APIC use.. even if > > you only stick a single core processor in.

Looking at e.g. [1], > it seems Windows does use the APIC even on UP. Socket A CPUs are also ungodly common. They're as common as slot 1/socket 370 Pentium 3s, and, at least with my old P3 board, trying to use APIC on UP caused lockups. My Duron 1ghz laptop also does the same thing. (Booting either with noapic fixes it). So yeah, if distros make stupid choices like these, then we're pretty screwed. > cu > Adrian > > [1] http://www.microsoft.com/whdc/system/sysperf/IO-APIC.mspx

Microsoft mandates the presence of an APIC implemented per MADT and all hardware interrupts connected to an IOAPIC for all servers and desktops with a "Designed for Windows XP" sticker. This implies more or less that a working APIC is present in all non-laptop x86 UP systems manufactured during the last 5 years. cu Adrian

Without noapic it doesn't get any interrupts for some reason. If now is the time to fix those bugs, I would be happy to try a new kernel and get you the dmesg + result of plugging in an usb mass storage device and reading from it on a DAILY basis. If you need anything else to resolve the issue, I would be happy to help out here. Maybe a pattern can be detected, which could help others. If you like to blacklist this machine by DMI, that would also help me. Many Thanks! Best Regards Ingo Oeser

Yes, please send those. It'd be best to get the info into bugzilla too - this doesn't look like a quick-fix scenario.

(that's important to know versus regression) Also does this machine use ACPI for interrupt routing? That's also important, because if you're NOT using ACPI, "noapic" means that you're using the PIRQ for irq routing and not MPS, so you're not "just" changing apic behavior, you're actually using a different BIOS table. (and to be honest, a buggy bios table is more likely the cause ... ;)

Andi has a nice patch in the suse kernel which adds heuristics to disable apic on systems where it isn't likely to work. It DTRT in at least one problem case that I know of. The actual fall-out from enabling 'run SMP kernels on UP i686' for FC6 has mostly been a non-event. Literally a handful of cases, that will likely all get caught and worked around by Andi's patch or similar. Dave

I haven't pushed that recently because i was busy with other things, but needs to be revisited yes. One broken case that still happens is that the patch assumes working SMBIOS. When there is no year in SMBIOS it will turn off APIC because it assumes it is a very old system. But sometimes new systems who would like APIC have illegal or broken SMBIOS year. On very new systems it isn't a problem again because those tend to have multiple cores. That could be probably a bit more clever. It's always difficult to navigate around all kinds of BIOS bugs. -Andi

This is unfortunate :-) alloc_super initialises s_op to '&default_op' and it isn't cleared on unmount, so the implication seems to be that i_sb has been freed and the memory has been reused. This tends to suggest that generic_shutdown_super isn't releasing all inodes before the superblock gets destroyed. I cannot see how this could be happening yet, but it might be helpful to compile with CONFIG_DEBUG_SLAB and maybe even CONFIG_DEBUG_PAGEALLOC. That might make the problem trigger earlier and so be easier to track. NeilBrown

That would permit most of generic_shutdown_super() to be bypassed, including the check that all the inodes have been consumed. David

Alex, where do we now stand with the various problems you've reported here? Is 2.6.20-rc7 still being bad?
Please reopen this bug if it's still present with kernel 2.6.20.
