Where do I send APIC victims?

Where do I send APIC victims?

[Roger Luethi]

As the maintainer of via-rhine, I get bug reports that almost in their
entirety are "fixed" by turning off APIC and/or ACPI. This has been going
on for several months now. Every now and then, something promising gets
posted on LKML, but so far if anything I've seen an _increase_ in those bug
reports. Maybe a fix is floating around and this will be a non-issue RSN. I
simply can't tell, since I don't have any IO-APIC hardware to play with.

Instead of just telling everybody to turn off APIC, I'd like to point bug
reporters to the proper place and tell them what information they should
provide so it can get fixed for real. According to MAINTAINERS, Ingo Molnar
does Intel APIC, but the problems are with VIA chip sets. So where do I
send my users? Any takers?

Hi, I'm trying to develop patches for ACPI IRQ issues. 

Are these VIA KT333/KT400 chipsets? If so, there's a known bug in many BIOSes 
with these chipsets. I'm waiting on some docs from VIA to fix this issue.

That would be most appreciated.

Yes, at least some of them are. I often don't know, since the reports just
say "Rhine ethernet broke in the new kernel" (VIA based boards typically
come with Rhine ethernet integrated into the south bridge).

Which still leaves the question of why it used to work (or made the
impression it did) with older kernels.

I think on earlier kernels there was a bug in ACPI which prevented it from 
being used for PCI IRQ routing. I know this was fixed somewhere in the 2.5.5X 
series.

When this bug was fixed, it unfortunately caused my nforce2 board to stop 
working because of other IRQ issues, which is how I got into this. Its likely 
the same thing causes older kernels to work with Via motherboards to work 
'cos ACPI isn't being used for IRQ routing.

2.4.22 has the ACPI from 2.6 backported into it, (which includes my patch for 
nforce2 boards) so it will start having the same issue with the BIOS bug in 
KT333/KT400  boards.

It does - 2.4.22pre7 is great on my boxes, 2.4.22 final ACPI is
basically unusable on anything I own thats not intel.

I can't back that. At least on all my Serverworks boxes there are no problems
with ACPI. I got reports from VIA-bases SMP boards that they are doing well, too.
(all for 2.4.22)

[Vladimir Lazarenko]

On my board, A7V8X, ACPI/APIC works just perfectly with 2.4.22 and KT400 
chipset, alas on A7N8X Deluxe board with nForce2 chipsets it causes nasty 
hangups.
Machine just simply freezes, no oops, nothing whatsoever.

Disabling APIC solved the problem.

And I can say that my Soyo SY-KT600 Ultra (VIA KT600+8237) has ACPI
problems as well. pci=noacpi doesn't help but acpi=off does. It gives
lots of errors that the ACPI tables are buggy when booting claiming
my 8237 SATA controller has gotten IRQ -19 for instance.
Using acpi=off solves the problem. This is with or without the libata
VIA 8237 SATA driver. Without anything it recognizes the chip but
doesn't like using IRQ -19 and doesn't see any disks. With pci=noacpi
it sees the disks but bombs out when trying to get the partition table.
It gets IRQ -19 still there. acpi=off makes it all work.

The IRQ -19 thing is a bug in my nforce2 patch in 2.4.22. It didn't drop back 
to using the PIC correctly. My latest acpi-picmode patch (posted to this list 
a few days back) corrects this, among other things.

Can you please resend me the patch?

Have you got any feedback on it?

Does it indeed? Sounds like that BIOS doesn't have the bug! Can you send me 
your /proc/acpi/dsdt so I can see what is different? Be really good if I can 
nick the code out of that for the other boards!

Does it work with ACPI disabled, but APIC enabled?

I have a board like this too.  It works fine with 2.4 & 2.6.  The only
trouble I've had has been a hard drive.  (hardware)

I've collected a few 2.4.22 ACPI problems and sent them to the ACPI guys.

Randy, Len? Any update on any bug?

Alan, mind sending us detailed reports of the ACPI issues with 2.4.22, 
too?

Re: [ACPI] Where do I send APIC victims?

[Sérgio Monteiro Basto]

Well I am one APIC victim since Jan 2002. almost 2 years.
I suggested build one database of "APIC victims" 
"Hi I would like make a database of the computers that have to Turning
off APIC.  Model, mother board and chip set, processor type ,  and DSDT
signature.
And put in blacklist.c to give this exactly warning."

But what I would like to say here is: I try to understand where kernel
hangs when I enable APIC and doesn't hangs when IRQ routing is setting,
but hangs before, exactly when try to:
"evxfevnt-0093 [04] acpi_enable           : Transition to ACPI mode
successful." this message never appears.

PS: I just don't had begging  the database because, now,  I don't have
any time for that. But I had some ideas, like using  php to upload dsdt
bin and try automatically Disassemble AML to ASL using iasl as cgi etc. 

thanks

I was just about to post that I have a Soyo KT-400 Dragon Ultra (black) with a 
integrated VIA Rhine II that has this problem.  I would really love to help 
solve this problem if I can.  I can provide any info you need as well as do 
some testing.



I have been using Mandrake, so I have been experiencing this because they have 
acpi turned on by default since a year (9.0).
