Hi All,
I working on ARM juno R2 board, with latest kernel 4.8.rc7 and I get
below USB EHCI probe error while booting with acpi=force.
Are you using the latest UEFI EDK2 ?
No, I am still using the UEFI binary which came as part of the Juno board.
[ 1.223662] VFIO - User Level meta-driver version: 0.3
[ 1.229335] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver

But this error goes off, if I don't force ACPI booting, i.e., if I
remove acpi=force from kernel command line , USB is detected and my
RFS which is in the usb drive, gets mounted successfully.
As I mentioned in private, I do get the same error if I drop _CCA in
USB object of ACPI DSDT. Can you give it a spin with latest UEFI ?
Sure, will try with latest UEFI.
I bet that's 8-12 months old. It puts the banner during boot with the
build date. You can try to follow [1] or access it from [2]
