 The Samsung 900X3F shuts down after boot with the message:
   acpitz0: critical temperature exceeded 144C, shutting down. The snapshot
   from September 17 was working fine. Since snapshot September 25 I'm seeing
   this.
   
   Strange thing: when I'm now booting the sept 17 snapshot kernel the 
   notebook
   also shuts itselfe down with the above message. Does th kernel modify the
   acpi tables?
   
  
  Now this is really strange: today I booted the Samsung notebook several
  times with the kernel from snapshot oct 5. The problem with acpitz0
  never occured. Can it be that the kernel sometimes is using a wrong
  address to read acpi stuff? Or is Samsung using a strange acpi
  implementation?

 Try turning on debug and see what it's really reading. There are some 
 dprintfs in there
 that will likely help.

I figured out that to fix this issue once such a shutdown happens I have
to leave the notebook turned off for some hours (usually I just suspend it).
Should it happen again I'll compile a kernel with option ACPI_DEBUG and 
post the resulting dmesg.
