Hello,
I have decided to make a pre-release of my 2.6.20 perfmon2 kernel patch.
It has been a very busy week chasing bugs on x86 and ia-64. I fixed a
serious deadlock condition in pfm_restart() today.
Before making a broader announce, and because I know many of you have been
awaiting this release, I have decided to release what I have so far.
I encourage you to test it and stress it. There may still be an issue that I
need to chase down, that is why a make a limited release.
There are no new feature in this release, simply some code restructuring
especially with the arch-specific layer. Several important bugs have been
fixed related to set switching and in-flight interrupts.
Please try it out, and report any suspicious results.
Hopefully by next week, we'll have something that I can release to the
wider audience.
You can grab the pre-release at:

Thanks.
Starting to look over the patch for the 2.6.20 kernel.
In base.diff is the reason there are not matching enter_idle() in the
various functions x86_64 and i386 is because the loop in cpu_idle()
has the enter_idle()? I noticed that the ia64 code had matching
exit_idle() and enter_idle().
