Unless you can reproduce your crash without binary only drivers such as the 
nvidia one your bug report cannot be acted upon.

I tested this _A_LOT_ and it doesn't matter if I
use "nvidia" binary drivers or x.org's free "nv" or
have just a text console with no X at all.
It happens on a production machine :(

Most easily to trigger this bug is to use USB2.0 epson
scanner over and have scanbuttond running - it will poll
scan buttons via usb2.0 and crash

Either hire a professional sysadmin, or disable CONFIG_PREEMPT

I tried it also with SMP enabled and disabled PREEMPT and
big kernel lock preempt - it also crashes.

So there's no need for a yet more professional sysadmin I guess.

Try it yourself on your machine if you have handy some intel 925X series
to crash.
I did it on 2 asus p5ad2-e premium boards, they both crash the same way.

Um, he said "production machine" not "web server".  There are lots of
applications that require preemption.

HI

Due to popular demand I'm mailing the recent crash
captured with serial cable on 2.6.16.19 on intel 925X
triggered with SMP + USB2.0 combination.

Here we got it, it's pretty random and useless for
tracking the real problem so please don't blame
software demux in DVB core just becaise it randomly
crashed there - only thing that matters is that a800
terrestroal receiver was running in USB 2.0 mode in
order to generate enough usb2.0 traffic
to trigger SMP+EHCI bug.

I contributed myself to the dvb software demux code
and it runs stable with it's demux core part almost
unchanged for 2 years.

If I remove EHCI and run a800 in USB 1.1 mode everything
can run stable for any amount of time.

Re: SMP HT + USB2.0 crash

HI

I downloaded memtest86 iso image and let it running. I passed
1st battery of tests and continues. I'm pretty sure it will keep
pass those test without anyerrors, after all memories there
are 2x512MB samsung and for this machine I was choosing
ram's recommended by the manufacturer this motherboard.

Regarding nvidia, I don't like their binary policy but I may
tell you that both intel 925XE machines can run indefinitely
(for days even months until I reinstall new kernel)
each with a lot of simultaneous openGL with nvidia on 2 monitors
in dual head, dvb receiving over usb (here I mean USB 1.1 only)
firewire traffic, SPDIF output, ethernet traffic on both interfaces
and all that
through enabled SMP, PREEMPT and PREEMPT BIG_KERNEL_LOCK
and it is not going to crash.

As soon as I enable EHCI there it comes.
Otherwise I have option to use EHCI and don't use SMP
but not them both.

I tested it with kernel 2.6.15.7 with nvidia
7174 drivers from which syslog's this oops capture
probably came from but the same thing but less frequently
happens with kernel 2.6.16.19 without nvidia drivers
(nvidia 7174 can't be compiled for 2.6.16.19).

For 2.6.15.7 it takes 2-10 minutes to crash, while for 2.6.16.19
it takes 1-2 days to crash. Yes it is more stable.
Usually it reports the similar oops like I supplied, but sometimes
also 2.6.16.19 reports SMP type crash - sorry I didn't have serial
console connected and didn't write it down - it looks different than
usual oops, contains less registers and no call traces showing
where in the source it crashed (I have never seen such oops before).

2.6.16.19 was running in console only mode and only with
drivers shipped in kernel. No external binary for nvidia, no
external source for ethernet. As the crash location report was
not indicatve to which module caused it, I was removing
one by one suspect module (dvb, firewire ethernet etc) and
reinserting them again until I narrowed it down to the
combination of SMP and EHCI that caused the crash.
Removing either of them makes the machine stable

Please attach another log without NVIDIA ever having being loaded. This is a 
technical forum, we need precise facts "nvidia has not been loaded", not 
vague recollections "nvidia probably wasn't loaded some time before".

Secondly, I highly recommend running memtest86 on your system for at least a 
couple of passes. You can download an ISO from the homepage and boot it from 
a CD. If this fails, you have faulty memory.

that's not just a vague recollection: nvidia 7174 from debian's nvidia
legacy source
could not be even compiled and therefore also was certainly
not loaded for 2.6.16.19. But for this special occasion I am going to
reproduce this sucker on 2.6.16.19 once again with quite minimal
stuff compiled in. I can even connect serial cable and get a laptop
capture the bloody oops just to find out which kernel boot option is
for serial console :(

hmm I don't know why I didn't use memtest86. but I usually test memory on
new machine linux, by continuously gzip-ing and ungzip-ing
4GB file for 2 days and verify if the beginning
and the end file  are the same memory, CPU and a bit of
hardware handling them together should be good...

The reason I'm suggesting memtest86, is that it can detect very subtle errors 
(gzip will not do this). The crash you're experiencing is in core kernel 
code, and it is very unlikely to be a real bug.

This is why Con and myself have suggested to reproduce without the binary 
junk, and why bad memory could be a very probable cause.

SMP HT + USB2.0 crash

[davor emard]

HI

I have an asus MB with intel 925XE chipset and hyperthreading capable CPU.
Certain lockups with random oops occur all through kernel 2.6.16.19. Some of
lockups are SMP only oopses (sorry but I didn't catch them exactly to a file),
other are usually like this attached file

As a general rule, if both
1) SMP
2) EHCI (usb 2.0)

Are enabled and USB2.0 devices are used frequently, then
kernel lockup appear between few minutes and 1 day. It is very annoying

Disabling either SMP or the EHCI fixes the lockups. Probably some
missing spin_lock or whatever in EHCI...
