2.6.9-rc2 and Hyperthreading. (SMT)

2.6.9-rc2 and Hyperthreading. (SMT)

[hotdog day]

I have been testing the 2.6.9-rc1, and 2.6.9-rc2 kernel patches over
the past couple days and have been having some issues with
hyperthreading (SMT) turned on.

This problem first exhibited itself when I was testing 
2.6.9-rc2-mm2-love2. I noticed the following quirks that ONLY show
themselves with hyperthreading enabled on my 3.0C Pentium 4.

Random HARD LOCKS. No messages from the kernel. Just a good swift hard lock.

Hard locks when mounting two cdrom drives in quick succession. 

Turning off hyperthreading solves these issues.  Going back to 2.6.8.1
solves these issues.

I then tried 2.6.9-rc1 with no mm or love patches. I had the exact same issues. 

Today I downloaded the prepatch to 2.6.9-rc2 and applied it to clean
2.6.8 source. The issues are still there.

I hope someone is paying attention to the way scheduler tweaks and
changes are affecting SMT enabled kernels. I don't think anyone wants
to disable features of their hardware in order to run an optimized
scheduler.

Try turning off CONFIG_SCHED_SMT and see how you go. Thanks.

Re: 2.6.9-rc2 and Hyperthreading. (SMT)

[hotdog day]

Turning off CONFIG_SCHED_SMT has apparently fixed the issue. 

Three Q's:

1) Am I taking some kind of performance hit by doing this?

2) Is this something we can look forward to seeing fixed?

3) Do you need any info from me to help you?

Thanks,

Troy McFerron

Does anyone have any other suggestions on this issue? I know others
who are experincing the same thing.

I have tested 2.6.9-rc2 on a 3.0 Ghz HT and all seams OK, results of LTP
message, and meminfo at:
http://quasar.cse.unsw.edu.au/~dsw/public-files/x86

Not extensive though no lockups and left running overnight.

Well, I took your suggestion Nick. I cnanot recreate the lockup when I
am not running X. It happens with both the fglrx module AND the radeon
module.

Darren, could you send me your kernel .config so I can do a diff and
see what you might be doing differently?

So my tests have been without X so I will rerun with X on.
