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

Same problem as reported yesterday in 2.6.22.1-rt2 in a T61 laptop, boot
hangs, last BUG printed is similar to this (numbers changed since
yesterday, of course, functions listed appear to be the same). No serial
port available to dump everything...

This was copied from the screen yesterday:
