  Binary package hint: linux-image-2.6.17-10-386
  
  Hello.
  
  I have a Fujitsu l1310g based on ati IXP chipset with radeon Xpress 200M
  
  Recently discussed on the forum, some of us (and looks like more and
  more with different types of notebooks) are having this problem.
  
  Sometimes when you boot the laptop, after the splash screen appears, the
  laptop fan stops. When it works, works like it should be, not always on
  (going much better than dapper). But sometimes doesn't work at all, and
  the laptop overheat.
  
  I've been unable to see anything weird at the logs, dmesg and stuff, and
  at /proc, the fan part, it reports that the fans are on (the two that
  comes with the laptop).
  
  Booting with 2.6.15, the fans works like it were on dapper, always on.
  
  If I boot on windows when i have the fan stopped, and then boot on edgy,
  the fan works again.
  
  When the laptop is overheated, i have to wait to cool it down, to try to
  boot again with edgy, because if i don't do that, every other boot
  resolves in a non-working fan.
+ 
+ This problem seems related to the psmouse module: 
+ @See [ACPI problems and solution] http://www.wolframschenck.de/nx6325.htm
+ 
+ The ACPI problem is threefold:
+ (1) The psmouse module is compiled directly into the kernel. This causes 
rebooting into a "bad state". If Linux is directly started after a reboot or 
shutdown from Linux, ACPI freaks completely out including the read-out of the 
battery status.
+ (2) The DSDT table of the bios seems to be broken regarding the methods of 
turning the CPU fan on.
+ (3) ACPI events are not processed properly in the kernel.
