[intrepid] system doesn't shutdown properly

[Axel Kellermann]

With kernels 2.6.27-7 and up (currently I have 2.6.27-9) my laptop doesn't shutdown properly anymore. If I try to turn it off, it freezes during the last stages of the shutdown procedure and doesn't power off (leaving the fans and the LCD backlight on). The last few system messages I get are:

* Unmounting temporary filesystems...
* Deactivating swap...
* Unmounting local filesystems...
* Will now halt
halt: unable to iterate IDE devices: No such file or directory

I also noticed that my syslogs are full of ACPI error messages that I didn't get with pre 2.6.27 kernels. Maybe that's an indication for what's going wrong?

Hardware: Acer TravelMate 4002LMi

OS (according to lsb_release):
Description: Ubuntu 8.10
Release: 8.10
Codename: intrepid

I'm closing the bug as the issue seems to be resolved with kernel 2.6.27-11.

@diaboflo: If you still experience the problem, feel free to reopen the bug.
