we are pleased to announce the v2.6.22.1-rt3 kernel

Attention! 

Ingo is off for a long weekend and therefor the download location for
this release is:

 http://www.tglx.de/projects/preempt-rt/2.6.22.1
  
more info about the -rt patchset can be found in the RT wiki:
  
   http://rt.wiki.kernel.org
 
This release is bugfix release:

- update of the x8664 -hrt queue (resolve boot problems)
- gtod vsyscall fix from Gregory Haskins

to build a 2.6.22.1-rt3 tree, the following patches should be applied:
 
   http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.1.tar.bz2
