[ also +Len Brown -- would you please comment what the ACPI-related bug in BIOS could be causing? Should be the message be logged also under 3.8.3? It does NOT happen! ] Hi Ying, I see the linux-pci throwed away the email dmesg and lspci attached. For the sake of archives I am including here some ACPI-related stuff.

Somehow, that did NOT happen for 11:00, the card in the express card slot (it was inserted before cold boot).
