Description Peter Johnson 2008-05-15 20:15:32 UTC 
My ICHR9 based mobo won't boot with legacy usb keyboard turned on (which I quite fancy for using grub)

I did some googling and testing and came upon a solution, but I have no idea how to implement a quirk like this.

LEGACY_USB_EN needs to be disabled during calibration or the wrong result is returned.

debug patch

Can you try the debug patch please?
I found enabling acpi will disable all SMI bits in specific acpi registers.

x86 and amd64 have been split in the kernel now, ioremap.c no longer exists.

Mmm sorry totally forgot about it, unable to replicate it on newer kernels so  was unable to test the patch. Fixed enough for me.

Feel free to close or whatever needs doing.
