When my Dell D600 is docked pressing the 'undock' button causes the kacpi_notify process to go into an infinite loop and eat all my CPU. Only a reboot helps to fix this. I`ve attached my dmesg and DSDT tables. You may be interested in the message, that appears in dmesg after pressing the 'undock' switch: ACPI: \_SB_.PCI0.PCIE.GDCK - undocking Reproducible: Always Steps to Reproduce: 1. Boot the laptop (when docked). 2. Press 'undock'. 3. Watch the system become unusable.

It looks like this has been resolved by upstream. We will monitor the patch for inclusion into Linus mainline dev kernel. The patch was just submitted to the linux-acpi mailing list on 8/11. [1] From the mailing lists responses, it looks like they are targeting 2.6.28 for these patches as the upstream developers have reservations. The only workaround I was able to see was acpi=off, which isn't such a great option for everyone. [1] http://marc.info/?l=linux-acpi&m=121843695710710&w=2

I got the same problem: kacpi_notify and kacpid uses ~90% of the CPU and unable to kill them (kernel processes) just after I disconnected the AC plug. I applied the patch [1] (change ACPI scan order) on my kernel 2.6.26 (Debian Sid 2.6.26-4) and the problem is fixed! I'm using Debian Sid on a Dell Latitude D520.
