cpuinfo + two oopses in a tarball.

Description of problem:
I get crashes and system corruption after a hibernate.  

Version-Release number of selected component (if applicable):
kernel-2.6.29.5-191.fc11.x86_64

How reproducible:
most times

Steps to Reproduce:
1. boot up  ; use computer for web browsing etc
2. hibernate
3. start computer
4. use alt-sysrq-s  /alt-sysrq-u / alt-sysrq-b to try to recover
5. recover system from filesystem corruption via boot disk and manual
file system checks
  
Actual results:
Corruption of X display; processes failing; actual kernel oopses
The file system is corrupt after this but the system doesn't realise that and boots without fsck.  Afterwards it hangs.  

Expected results:
Computer returns to normal

Additional info:
On FC10 this also happened but rarely and with a slow collapse; I wasn't able to reproduce it reliably so didn't get a report up.
