Did this work in any version of Linux before 3.2? If so, what is the latest version that worked? please attach the output from dmidecode BTW. there are a bunch of ACPI EC errors in your dmesg. It might be a good idea to file a separate bug on them. Reboot worked fine before 3.2. Kernel 3.1 is the lastest version that works. Created attachment 72401 [details]

PCI reboot quirk for Dell Precision M6600
please check if this patch works for you or not.
This patch works for me, the laptop reboots fine without reboot=pci now. Thanks. I'll add the new dmesg output just in case. Created attachment 72470 [details]
